MSI Mega SKy 580 USB2 DVB-T TvTuner PVR

[guiri]

I'm going to try the software on a clean install, and I'll get back to you

I installed just the 5.1.2600.1043 driver (I have the "Digital TV USB Mini Receiver" device) and the gbpvr software.

I still had the same problem; the scan for my local transmitter (Winter Hill) results in zero strength, zero quality.

I then installed the bundled PVR software and found that it scanned no problem.

I then went back to gbpvr and changed the device settings to All Region / All Channels, and I could then scan everything in.

I think the Winter Hill frequencies are not going to work with the mega sky. In file 0076.ini, the following are given:

Code:

1=C56,754166,0,0,8
2=C66,834166,0,0,8
3=C68,850166,0,0,8
4=C67,842166,0,0,8
5=C60,786166,0,0,8
6=C63,810166,0,0,8

I changed all the 166 to 000, and then it scanned Winter Hill fine. This is at odds with the scanning requirements of other cards (see this thread http://forums.nextpvr.com/showthread.php...nter+hill).

It might be that other megasky users are having a similar problem with the frequency definition of some specific regions (so try all regions).

Question for the developer of gbpvr (which I'm going to enjoy playing with now I can get some TV in it) ...

Can the tuning be modified so that it will take account of this type of device, to avoid this confusion? Or is it down to the poor BDA implementation of the megasky as mooted earlier?

Thats very useful to know.

I think its down to poor implementation of BDA drivers, or possibly even the tuner they've used on this device.

Sorry, I wont be changing anything in GB-PVR to account for this. Hopefully other megasky users will find this post though.

The method MSI have used does make sense. They probably intentionally ignore manually-specified 167KHz offsets to avoid duplicate channel issues in Media Center.

Media Center specifies every frequency +/- offsets, to compensate for older cards which need to be told the specific frequency including offset (i.e. they can't find it themselves).

Most modern cards auto-lock 125KHz/133KHz/167KHz offsets. If the card didn't ignore say 762166KHz, then you would end up with duplicates when scanning in MCE - one on 762000KHz (which autolocks to 762167KHz) and another on 762166KHz.

Hauppauge cards used to be told the exact frequencies (for MCE2004 compatibility I'm led to believe) but for the past year or so have auto-locked onto offsets (CX22702 can have auto-lock turned on or off).

The method MSI have used does make sense.

Looking again at the thread I quoted earlier, it seems some cards need the 166 offset in order to tune, but the MSI doesn't and therefore fails when tuning to the original 0076.ini settings.

Why is that the MSI tunes ok when using all regions? Is it that tuning is attempted at the centre frequency and also with an offset? I noticed duplicate channels in my channel list eg. ITV1 and ITV1 (1). Is this a side effect of the tuning implementation?

Right, because it has to ignore the exact frequencies specified in 0076.ini

You might get duplicates because one ITV1 is for the main audio stream, and the other is for the audio description stream.

As for an All Regions scan, I'm not sure if GB-PVR just goes CH21, CH22, CH23 etc or CH21+167, CH22-167, CH22, CH22+167 etc. Either way, just specifying the base CH21, CH22 etc frequencies will be sufficient - any of the others will be ignored.

I recently bought one of these, and have never recieved anything.

I live in a fairly strong signal area, our freeview box can work fine of a small set-top aerial, but have never had any signal on my PC.

I've tried using the included aerial as well as the set-top aerial which works so well on a freeview box, but nothing! And I mean absolutely nothing!

I've never seen anything other than 0 in both the signal strength and signal quality in both the bundles Presto! software and GB-PVR.

I'm starting to think I'm either missing something major, or I've been sold a dud.

The only thing left to try is to somehow connect my PC to the roof aerial, unless anyone has any other suggestions.

Hello everyone, i am writing for first time such forum so if I don't seem to know how to be so skilled in writing this messege please excuse.
Couple of days ago i bought MSI Mega Sky 580 USB2 DVB-T tuner with Presto! PVR. I have been having problem with starting the Presto! PVR so I was searching in internet for some solution but I couldn't find anything anywhere that relates to the problem i have been experiencing so I am posting here to ask your help although I know that this thread might have been made for some other purpose.
Installation was not problematic, both hardware and software. When I see device manager the hardware is recognized. When I look into the list of installed software, Presto! PVR and Digital TV USB Mini Receiver are there. It was when I try to start the Presto! PVR that there was the problem. Cursor blinks about a second but then nothing happens.
I tried updating the software, applying patch, disabling firewalls antivirus software (norton), reinstalling the software and driver, and everything i could think of that might be cause of the problem but nothing helped.
My laptop fufills all the requirements and there is no other program that doesnt work so this is th first time i am experiencing this kind of problem. Usually it was like i would get an error message or something so that i would at least know that there was a problem. But with this there is nothing. So it is very difficult for me figure out what to look for. Do you think it is problem with Presto PVR? or is it a problem with the driver? or is this software in conflict with some other program? I would really like to make this thing work so I would appreciate your help very much.
Thank you.

The problem is that the included drivers on the disk are borked ...get the newest drivers from the msi website and you will be ok ... I cant remember if I removed the old software before installing the new but I could suddenly pick up way more channels and it no longer stops responding ....
it was a cheap tuner and I wasnt expecting much and I was not disappointed

I've been fighting to get this tuner (MSI megasky 580) to work properly with GBpvr for a while now, Using the Uli M9207 card definition, I find that the tuner typically fails to pick up anything whether I scan all regions, or just my transmitter (sandy heath) - whether I specify offsets to the base frequency or not. I believe that in fact GBpvr is not managing to get the tuner to change frequency. I base this on the fact that if you tune in a channel in another application then quickly exit and run config, the scan finds the channels located on the same mux as that which was tuned in the external application, regardless of the frequency it claims to be scanning. This belief is backed up by the fact that, having fooled Gbpvr into finding some channels in this way, if I try to rescan the channels whilst one of the currently found channels is showing in the preview window, the preview keeps showing live tv whilst the program thinks it is scanning various frequencies, I can not see how this would be possible for this single tuner device. So if, as I suspect, the problems I am having are related to the tuner frequency not being altered at all by gbpvr, does anyone have any bright ideas why, and indeed how we may fix it?

I've completed all instructions found on this forum as I too can not get Presto to work. But even the GBPVR come up with a similar problem no display.
When I scan for channels I see what the channel is showing no problem but when I run the program all I get is ERROR: OBJECT REFERENCE NOT SET TO AN INSTANCE OF AN OBJECT ?? sorry means nothing to me any ideas please.. Thanks.
