Problem with DirectShow?

[bachjoy]

I've been using GBPVR for several days and love the program. Initially everything worked perfectly, well except for the media mvp, but that was because my wireless network card is junk and now works fine as I have a wired connection. Anyways, now my pvr150 is not working properly in GBPVR. It appears to be running a lower resolution than it previously did, and also has issues with about half the channels. What is occuring is that for a nanosecond when I change the channel the picture is clear as a bell, and after that it almost appears as if there is an overlay of static. Using the supplied Hauppauge software, the tv works great, and also with MediaPortal. I did reinstall the software, wiping away the directory in the process. I was experiencing issues with my older tv card, and ati all in wonder, and uninstalled its software, but I can not recall if the problems begam immediately after doing so. I'm assuming this is a directshow issue as other programs, namly windows movie maker feature similar static when accessing the tv card. This continued even after I uninstalled (using hauppauge's utility) and reinstalled the software for the pvr150. Does anyone know of any fix to this problem, other than wiping my entire computer and reinstalling windows? Is there any other information I can give which would help pinpoint my issue. My TV tuner is a pvr150, on a Dell Dimension 8100 (P4 1.7 GHz, with 512 megs of ram. The video card is an ati all in wonder 9600, with the tv software not so cleanly uninstalled (the uninstall process crashed towards the end).

I think it could possibly be a registry key that is forcing my tv tuner to either preset to another country at a lower resolution, and tune in antenna mode, but I could be completely wrong about both my hypothosized cause and symptoms.

What MPEG2 video decoder are you using?

[bachjoy]

The Hauppauge Decoder, by main concept. I have tired it with others including the Intervideo NonCSS, but there is no change. Currently I am reinstalling the ati software to see if that fixes anything the ATI software might have broken. I will post back with how it turns out.

[bachjoy]

Well the reinstall of the ATI software doesn't work, what MPEG decoder would you reccommend that I use?

I dont even know if its related to that. It just seemed a likely candidate to me. Another possibility is if you have ffdshow installed on your machine.

Having the Elecard software installed on my machine has done bizarre things in the past.

sub, thanks for all your help

Would decoder issues have a similar effect on both the playback of programs recorded before the problems began and the viewing of live television? I can play old mpeg recordings made before my problems began just fine in GBPVR.

Is there any chance that the tv card is ignoring the country and input type settings in gbpvr? I ask this because when I used to use the tuner in the ATI card, I had an issue where one program could not change any of the settings for the tuner, yet another program could. Both these programs accessed the tuner through DirectShow. Would the clear picture then snow when I first enter the tv module, even be symptomatic of that or would the picture be universally bad?

Can you post a screenshot of it in action so we know what you mean exactly?

Some people in PAL countries have found that the ATI cards use a funny 720x480 PAL mode by default, so they end up with bottom of the picture being (between rows 480 and 576), but the bit that was captured looks fine so this doesnt sound like your problem. The work around for this was explicitly setting the ForceStandard setting in direct.ini.

Is there anything glaring that I am missing? Sherlock claims that nothing is broken. (I'm really hoping its a codec issue as that can be easily resolved. If its a DirectShow issue, you know what I'm doing this weekend)

GB-PVR doesnt set the resolution at all for the ATI 550 pro cards, so if this was the last resolution you used in the ATI software, its possibly still using it when recording in GB-PVR.

Sorry about the semi double post, I didn't think the first one went through and wanted to add more info. Oh, I'm sorry if there is any confusion, I'm not trying to use an ATI card in GBPVR, only my pvr150. I stopped using the tuner in my All in Wonder a week ago because it was troublesome and I had been wanting to get a HW card and the pvr150 was on sale.

Anyway, attached is a picture of what I seeing. When I first tune in a channel for a brief instant you see a perfect picture, this is literally a blink of an eye. Then the channel shifts betweeen colored and grey static of varying degrees. The worst channels have no audio. I'm located in the USA, recieving my signal over cable. I know the cable signal is fine because the WinTV2000 app captures just fine.
