Sub has given me some great help for the TV Walker which AFAIK, isn't covered specifically in the WIKI docs, but is spread around the forum posts, so I'd like to make a small contribution, mainly for the Lifeview TVWalker Mini, most of which (I believe) also applies to the PX-M402U and other GO7007SB devices.
If this isn't helpful, no worries, folks can still trawl the forums. If anyone wants to correct/change it before (IF) it gets wiki'd please feel free. I am very new to all this. It's just an idea to put it all in one place.
The TVWalker and other GO7007SB devices.
<Sub notes> Nearly all the discussions you read on muxes on the GB-PVR forums (since the beginning of 2005) relate to BDA support. You get the occasional post about muxes in relation to GO7007SB devices, but this is pretty rare. Very few GB-PVR users are actually using these GO7007SB devices, whereas BDA users are pretty common now. To do a recording with the GO7007SB devices, it needs a couple of software components which are installed with the software supplied with these devices. The LifeView TVWalker ships with TVR, from which GB-PVR uses the HT audio encoder and mux.
The Plextor devices ship with Intervideo WinDVD Creator, from which GB-PVR uses the Intervideo audio encoder and mux. (whilst this is the general rule, if it doesn't find the HT ones, it'll look for the Intervideo ones.) Even though they offer MPEG4, these devices aren't that great compared to the Hauppauge devices, which do everything in hardware. <end of Subs note>.
MPEG2 Decoders and Muxes for Dummies (or what should I install to get my TVWalker running with GBPVR?)
Very simply put, the decoder is used for VIEWING and the Mux Filter is used for RECORDING.
A. MPEG DECODERS
i. A TV Card or USB Device has a Tuner which feeds the input signal to the (Hardware) MPEG2 (can also be DivX or MPEG4) encoder. For this encoded video/audio stream to be played back by GBPVR on your PC or television you need an MPEG2 (or DivX/MPEG4) DECODER to be able to "read" this video stream. MPEG2 decoders that generally work with GBPVR are covered quite well here in the WIKI, http://gbpvr.com/pmwiki/pmwiki.php/Config/Playback and appear to be generic to all cards. Find one of those, or more and install it.
Note that GBPVR only supports Devices with HARDWARE Encoders, although there are plugins for SOFTWARE Encoders.
ii. The SVideo / Composite inputs are like bypasses that feed a signal directly to the MPEG2 encoder. You STILL need a DECODER!
iii. Cards that "capture" Digital Video Broadcasts (DVB) do NOT need an MPEG2 encoder, as the DVB broadcasts are already encoded as MPEG2. You STILL need a DECODER!
v. The default MPEG2 Decoder can be viewed easily by installing Microsoft's DECCHECK, at least in WinXP. You can even use this utility to change the Windows XP default (which is also the GBPVR default if no defined codec is chosen) using the WinXP DECChecker. See http://www.microsoft.com/downloads/detai...laylang=en
i. The TVWalker uses the HTMpgMux.ax installed with the TVR Software as the Muxer. You can ALSO install WinDVD CREATOR which will install another compatible Mux. The Trial Version will work fine. Muxers that are used are Tuner Card or rather chip specific. The Cyberlink PowerDVD or Intervideo's WinDVD or Showshifter Muxers that work on BDA Devices will NOT work with the TV Walker, so don't think if its OK in the Muxchecker for the BDA devices it will work!
The current MuxChecker utility is only really relevant to BDA digital devices. It also only checks for muxes that are used by the BDA support, namely the Cyberlink/Intervideo/Showshifter muxes. It wont actually show the HT mux in this list since this wont be used by the BDA devices.
This specific mux performs a slightly different task, and for this specific need GB-PVR only looks for the muxes that are supplied with the GO7007SB devices (InterVideo and HT).
ii. All the current HTMpgMux.ax files from TVR 2.27, 2.28 and 2.29.4 are version 1.0.0.1 and all are the same file size.
iii. IF HTMPGMux gives you an error, just de-register it and it will default to the WinDVD CREATOR Mux. (To be confirmed).
Q. Why do GO7007SB devices need a different Mux Filter to the BDA Devices. What's wrong with the WDM Drivers?
A. The PX-M402U and other GO7007SB devices do have WDM drivers, and in fact GB-PVR uses them. Having WDM drivers does not mean it'll magically start working with all sorts of applications. The applications still need to be written in such a way that they can understand the type of information produced by the WDM drivers (in this case DivX/MPEG1/2/4 not YUV as used by the WDM drivers of many of the older software encoder cards).
The only reason GB-PVR requires WinDVD Creator to be installed, is because the hardware on the GO7007SB devices produce PCM audio, which is less than desirable and not compatible with the MPEG standard. These WinDVD Creator components are used to "on-the-fly-encode" the audio to MPEG1 Layer II audio, and to mux it back into the MPEG file. There are alternatives to the WinDVD components, as some of the GO7007SB ship with different software which performs the same task. For example, the LifeView TVWalker ships with the HT components."
Q. If I can't use the BDA Muxchecker how do I check what Mux Filter is installed?
A. Download a Filter Manager.
Q. If someone says "register (or unregister) a filter, what does that mean, what do I do?
A. Follow these guidelines:
To Register a Filter manually e.g. HTMPgMux.ax , in Windows choose start, run and type regsvr32 <PATH> HTMPgMux.ax
To UNRegister a Filter manually e.g. HTMPgMux.ax , in Windows choose start, run and type regsvr32 /u <PATH> HTMPgMux.ax
IF the Mux FIle is already IN C:\WINDOWS\SYSTEM32, you do not need to type the <PATH>. Do NOT Type the "<>" brackets!
Well this is my last kink to figure out. I cant perfect the way my video looks. To explain what I mean, here is a pic:
I am having problems with rapid movement. Take for example, the ticker at the bottom of the screen. It always seems to be distorted, the same goes when (for example) a baseball players swings the bat.
Any ideas? I use VMR9 with the CyberLink video decoder. The other options are InterVideo and NVidia. The Cyberlink one seems the best?
This is running on basic COAX cable as well. Is there anyway to check what WinTV uses for the video codecs? Because the same channel looks a bit better. (Sorry for mentioning WinTV, this program is far superior)
For a while I've been looking for solutions to the random audio loss I was getting on certain stations using my Hauppauge PVR-150, and finally found that I could solve the problem when I fine-tuned the stations in WinTV.
I searched these forums to learn that I could use Tuning Assistant or FreqCopy to get this working in GB-PVR now. FreqCopy seemed like the easiest method so I ran that, but now it seems everything's off in GB-PVR. For most of the lower channels, it shows channel 2's signal (no sound) and doesn't change whenever I press channel up/down (though the OSD guide shows the changes in guide info) and most of the higher channels do similar things with other stations.
I attempted to undo this by deleting the "TV AutoTune/TS0-0" registry entry that FreqCopy copied to, but to no avail.
So, I guess I have two questions:
1) What can I do to clear whatever channel frequencies GB-PVR is now using and start anew?
2) Is there anything you can think of off hand that I did wrong when using FreqCopy?
Is it possible to have the EPG copied when using multiples of the same capture card? Right now it takes about 5 to 10 minutes to have the EPG processed when setting up a new verion of GBPVR from scratch. Seems redundant to do that each time I add the same card. Thanks for great work on the program.
I have a very basic setup. Just a coax cable going from splitter to PVR-250 card. I can watch tv, just cant change channel.
When I use the up and down arrows, the little channel name and description overlays at bottom change, but the channel doesnt change.
Also, entering 22 and then pressing OK doesnt change the channel either, it just tells me what is on channel 22. Its like GBPVR thinks the channel has changed, but it hasnt.
I tried using the 'direct access option' but nothing seems to work? I also put the .ini settings from the WIKI site into the remote and tried that but it didnt work either?
To enable the OTA HDTV portion of the Wonder, you need to add this to the bda.ini file:
[ATI DTV WONDER]
TUNING_TYPE=ATSC
FILTER_TUNER=ATI DTV Wonder Digital BDA Tuner
FILTER_CAPTURE=ATI DTV Wonder Digital BDA Capture
PIN_TUNER_IN=Input0
PIN_TUNER_OUT= BDA MPEG2 Transport
PIN_CAPTURE_IN=MPEG2 Transport
PIN_CAPTURE_OUT=MPEG2 Transport
Is it possible to have the recorded files to have the name of the program and episode title if any. At present I see the files recorded with only the program name.
Thanks.
Hi, trying to setup my ATi T550P to record from a composite source, rather than TV channels via an aerial. Using GB-PVR 92.11.
Set Source to 'Composite, External Tuner' and no tv aerial connected. So all channels just display the composite source. When trying to record the composite source on say BBC1 with no EPG data by timeshifting LiveTV, the recording gets split into 1min chunks instead of a single file.
Edit: nevermind, think I've solved it by updating to 93.10 and adding a channel manually instead of recording off a real channel like BBC1.
Is there a way to have all 3 of these work together properly?
When I use ShowAnalyzer in my postprocessing.bat, comclean screws up.
I get this every time, on every recording.
Here's my comclean.err
