Problems with Video outpn on PVR350

[Gedanken]

Up until recently, I had my setup working pretty well. I used an old 800Mhz processor with a PVR350 and a PVR150. Things work great except that about half the time, if both tuners were recording and both shows ended at the same time, the computer would hang up tight. I tried several different drive combinations but it never went away, but I managed.

And then the mother board died.

So I went out and bought a small formfactor box and a new mATX motherboard with a dual core AMD 64 bit processor and then the real problems began. After lots of driver gymnastics to get the proper drivers for the two tuner boards and support DLLs installed, it was up and running. But now, after I watch a prerecorded show or so, I the playback hangs. The computer is still responsive and I can watch the GBPVR app respond to the remote but the playback is either frozen or blank. If I restart the GBPVR app, it will sometimes reset the display and the OSD menus will work but if I try to play a video, the screen simply goes blank and I get no audio.

Checking the GBPVR.exe-native log, I see the following:

20:54:25.968 VERBOSE DirectShowHelperPVR350::ShowImageUsingPVR350()
20:54:26.031 ERROR SetOSDDisplayBuffer - IKsPropertySet->Set IVAC_OSD_DISPLAY_BUFFER failed

20:54:26.031 ERROR SetOSDState - IKsPropertySet->Set IVAC_OSD_STATE failed

etc.... (log is attached)

Suggestions?

I'm running XP SP2 currently. I just tranfered the disks from the previous system and reinstalled the OS to being it back up.

Attached is a log after a reboot, which allows the system to work again. In this case, the first show I watched eventually failed when I did a backward skip operation.

It doesnt look like those PVR350 drivers are functioning correctly. If I was you, I'd be thinking about uninstalling them and trying again.

I've reinstalled them a few times to no avail. After a reboot, everthing works fine until, at random, after a skip or similar operation the display goes blank.

Since this all worked before, I'm assuming it has something to do with the dual core processor I'm on so it could be a driver issue or an application side race condition of some sort.

I'll try locking GBPVR.exe to a single core and see if that helps. I'd appreciate any other suggestions.

maybe youve fallen upon one of the mobos that the 350 throws a giddy fit on. theres quite a few...i have a vague memory of reading something about it not liking Hyperthreading, so you might be on the right track with switching it to single core...

does it have the same behavior in software decoding?
