I don't watch much TV, but I watch enough that now my TV has decided to have no audio, I thought a cheap TV tuner for the PC would be worth getting. Seeing a £10 device at Amazon with good reviews, I grabbed it. It works, and comes with software that's okay but it's far from great, so I went looking for a replacement. GB-PVR looks awesome, but I can't set it up.
There's no brand name. That packaging just has 'Taiwan Technology' on the bottom. The USB driver is supplied by 'Silicon Vendor'.
I tried a good number of the available devices in the GB-PVR Tuning-Assistant list but none worked. Are there any generic solutions that'll work for me?
After installing GB-PVR on my WinXP machine, I always get this message when it tries to automaticlly run the configuration program, or if I manually try to run any of the executables. I've made sure I have the .NET Framework and nearly everything else I've found suggested on the forums, but this is so early in the game that it's hard to tell (I haven't been able to run anything successfully yet).
I can uninstall the program and reinstall it (done this a number of times) but I get the same result. Anyone have any idea what's up?
I've worked through a lot of the setup of TV Listings and have my batch files and all working. TV Listing itself is working well.
What I cannot get to work is the additional icons for resolution, new program..... I just have the standard TV listing. I am using xmltvExtras and it says it updates 7837 entries. I'm using Schedules Direct.
I'm not sure where to start debuging.
1. Do I not have the extra info from schedules direct
2. Is the EPG database not getting updated with the icons
3. Is TV Listing not finding the icons?
Thanks,
Coty

San Francisco - A team including the Electronic Frontier Foundation (EFF), Princeton University, and other researchers have found a major security flaw in several popular disk encryption technologies that leaves encrypted data vulnerable to attack and exposure.
"People trust encryption to protect sensitive data when their computer is out of their immediate control," said EFF Staff Technologist Seth Schoen, a member of the research team. "But this new class of vulnerabilities shows it is not a sure thing. Whether your laptop is stolen, or you simply lose track of it for a few minutes at airport security, the information inside can still be read by a clever attacker."
The researchers cracked several widely used disk encryption technologies, including Microsoft's BitLocker, Apple's FileVault, TrueCrypt, and dm-crypt. These "secure" disk encryption systems are supposed to protect sensitive information if a computer is stolen or otherwise accessed. However, in a paper and video published on the Internet today, the researchers show that data is vulnerable because encryption keys and passwords stored in a computer's temporary memory -- or RAM -- do not disappear immediately after losing power.
"These types of attacks were often though to be in the realm of the NSA," said Jacob Appelbaum, an independent computer security researcher and member of the research team. "But we discovered that on most computers, even without power applied for several seconds, data stored in RAM seemed to remain when power was reapplied, We then wrote programs to collect the contents of memory after the computers were rebooted."
Laptops are particularly vulnerable to this attack, especially when they are turned on but locked, or in a "sleep" or "hibernation" mode entered when the laptop's cover is shut. Even though the machines require a password to unlock the screen, the encryption keys are already located in the RAM, which provides an opportunity for attackers with malicious intent.
The research released today shows that these attacks are likely to be effective against many other disk encryption systems because these technologies have many architectural features in common. Servers with encrypted hard drives are also vulnerable.
"We've broken disk encryption products in exactly the case when they seem to be most important these days: laptops that contain sensitive corporate data or personal information about business customers," said J. Alex Halderman, a Ph.D. candidate in Princeton's computer science department. "Unlike many security problems, this isn't a minor flaw; it is a fundamental limitation in the way these systems were designed."
In addition to Schoen, Appelbaum, and Halderman, the research team included William Paul of Wind River Systems, and Princeton graduate students Nadia Heninger, William Clarkson, Joseph Calandrino, Ariel Feldman as well as Princeton Professor Edward Felten, the director of the Center for Information Technology Policy and a member of EFF's Board of Directors.
The researchers have submitted the paper for publication and it is currently undergoing review. In the meantime, the researchers have contacted the developers of BitLocker, which is included in some versions of Windows Vista, Apple's FileVault, and the open source TrueCrypt and dm-crypt products, to make them aware of the vulnerability. One effective countermeasure is to turn a computer off entirely, though in some cases even this does not provide protection.
For the full paper "Lest We Remember: Cold Boot Attacks on Encryption Keys," a demonstration video, and other background information: http://citp.princeton.edu/memory/
Researchers with Princeton University and the Electronic Frontier Foundation have found a flaw that renders disk encryption systems useless if an intruder has physical access to your computer -- say in the case of a stolen laptop or when a computer is left unattended on a desktop in sleep mode or while displaying a password prompt screen.
The attack takes only a few minutes to conduct and uses the disk encryption key that's stored in the computer's RAM.
The attack works because content as well as encryption keys stored in RAM linger in the system, even after the machine is powered off, enabling an attacker to use the key to collect any content still in RAM after reapplying power to the machine.
"We've broken disk encryption products in exactly the case when they seem to be most important these days: laptops that contain sensitive corporate data or personal information about business customers," said J. Alex Halderman, one of the researchers, in a press release. "Unlike many security problems, this isn't a minor flaw; it is a fundamental limitation in the way these systems were designed."
The researchers successfully performed the attack on several disk encryption systems -- Apple's FileVault, Microsoft's BitLocker, as well as TrueCrypt and dm-crypt -- but said they have no reason to believe it won't work on other disk encryption systems as well, since they all share similar architectures.
They released a paper about their work as well as a video demonstration of the attack (below).
At the moment, the "Watch" button is at the bottom when you select a program. It would be good to have the option to either change the order so that it became the first button or have the option to press "Play" in the TV guide and miss the pop-up out all together.
The idea is that you have a menu of channel groups/types. When you select one, you then get the TV guide for that group.
For example, on my Sky box, you get a menu with options such as Kids, Movies, News etc. You select one of these and you then get the associated channel listings. It makes it significantly easier when you have a lot of channels.
You could also have the option to add a parental lock to a group.
Have purchased a new PC with Vista Home Premium. Installed GBPVR, USB-UIRT, IRCoomand2 and Sky STB having used all four successfully with Windows XP.
Everything works as it is supposed to except for changing channels to record.

i'd like to have the option to flag a show as viewed. i have some shows that either my wife or my daughter like to view as well, but maybe we can't watch it together at the same time, so it would be nice if when one of us finishes watching the show, we could flag it so that the next person will know it's okay to delete it when they are done.
PVRX2 always working sweet using VMR9 FSE.
But then decided to experiment with HD videos (again), on my rather ageing rig (Athlon XP2600, Geforce 5950)
Was suprised to find that, using COREAVC, I can play HD mkv's fine. But the old nemesis returned - screen tearing, yuck.
For the hell of it I installed .Net 3.5 and tried using EVR in PVRX2. Another suprise - the screen tearing 90% gone, and all video/TV looks pretty good (despite loosing hardware acceleration in EVR).
However EVR is not quite the holy grail. If I pause or FF/RW a DVD (rip) PVRX2 just freezes up, and will not respond to remote. However if I right-click on the screen, after a long pause, it goes back to the DVD menu, then if I select play on the remote it goes back to where I left off - very odd! Changed the DVD config option to 'Use DVD chapter skip', and that works fine instead of FF/RW, but pause still the same issue.
So am I alone in this odd DVD behaviour using EVR? BTW I have the Nativeutilities patch dated 26 Nov 2007, and am using Purevideo for vid & aud and DVD navigator. If I use Intervideo or Nvidia navigator, I can't play ripped DVD's as they seem to always look for a disc in the drive.

I installed klite megapak, but I had to deactivate ffdshow in order to get my high def stuff to play back stutter free. Apparently ffdshow was hijacking .ts and dvr-ms playback. However, now SOME of my avi's don't playback. Gspot claims that they are xvid mp4 but with some other stuff than usual (pvop or something). Most of my avi xvids play fine but there are some that turn up as nothing found. ffdshow use to handle these fine and I don't know what else to do about it. I should probably try fourccc or cccp or something, but I'm afraid to hose up my system now since most things are working ok.
I was curious if I did manage to find the correct filter, what would I do to make any file type like that permanent. I can connect the dots in graphedit, but does it make it permanent for only that file or for all files like that file is my question?
Please share your codec experiences if you could. What's the optimal codec that is all-in-one? Klite works fine, but ffdshow sucks up more CPU cycles than my dvr machine has. I use it on my desktop machine, but that one has more horsepower.
I guess one more question while I'm at it: how can I find out what ffdshow is doing? When I enable it, it takes over for certain file types, but I'm not quite sure what exact codec it is calling (and Gspot is not much help either).
