Capturing in Vista

...well someone had to finally admit to it! :sly: I recently completed a new computer build and for kicks I thought I'd go all the way and install Vista on it. The new capture card is a ATI Theatre 550 which works very nicely with Windows Media Center. VirtualDub 1.6.17 also works well aside from a couple of quirks and I'm curious if anyone else has experienced them. The first is if I enable audio preview while capturing, which is turned off by default. When turned off, video playback is nice and smooth (overlay mode), but turn it on and video becomes choppy. Try capturing with audio preview turned on and it's dropped frames city. It's not a big deal to capture with audio preview turned off, but it's something perhaps worth mentioning. Another issue I've discovered is if I enable the source preview window while encoding, the entire window will be green. Again, not a big issue as the final encode is fine, and I typically don't have it turned on in any case during an encode anyway (saves CPU cycles). I just thought I'd throw that out there. I have read that Avery himself hasn't yet jumped completely to Vista and honestly I'm surprised I didn't run into more significant snags using VirtualDub in Vista.

That would certainly help to explain the audio issue. I wondered if it were due to the new hardware abstraction model in Vista. It now appears that it may in fact be a likely cause.

Did you try with the latest drivers? ATI/AMD released new ones a few days ago (and frequently update). Have you tried capturing with VirtualVCR? I don't have Vista, otherwise I'd test myself.

I have tried capturing with VirtualVCR using my Terratec Cinergy 400 TV PCI card in Windows Vista 32-bit but I get audio synch problems when I select the TV card as audio source. Trying to connect it through the sound card does not work at all because my Cretive Soundblaster Live Value does not work to record any audio with (I think there is a driver problem). However I don't get any more dropped video frames than I get in Windows XP. So you say I get a performance drop in Vista audio using directshow. Perhaps I should try using a less demanding video codec like mjpeg or huffyuv instead of lagarith and see what happens. But I think my dual core AMD X2 should have power for video capture... Is there any workaround for the audio in VirtualVCR in Windows Vista? Regarding performance I tried to switch off the aero glass in the properties of VirtalVCR exe file and it seemed to improve a little bit. EDIT: My performance problem was solved by installing an other driver for my soundcard which enabled the audio inputs of the soundcard and then I could connect audio out of the TV-card to an audio input of my soundcard and use that as audio source in VirtualVCR.
