Audio mutes during capture

[VcdGeek]

I've recently upgraded to Win XP Pro and am using the WDM driver from http://btwincap.sourceforge.net. I have a Hauppauge tv capture card and am using VirtualDub. In the past week I've noticed that the audio stops about 1 minute into the capture. This also happens even if I'm using the preview mode on VirtualDub. If I re-select the source as Tv Tuner in the Source dialog, the audio comes back on but again cuts out after about a minute. Has anyone seen something like this? I'm at a loss. Thx

I've tried some more things to find a solution. First, I uninstalled the BtWinCap driver and installed Hauppauge's drivers - no luck - same mute after about a minute. Next, I tried booting back into Win ME (second partition) and under ME, it works fine - which rules out a hardward problem. I guess I will continue to capture in ME until I find out what's going on...
