I am trying to capture from VHS in AVI, edit the captured video, and then send the edited video back out to my Sony TRV130 Digital8 via FireWire link. I am capturing using VirtualDub, WinTV PVR capture card, and editing using Ulead VideoStudio 5. If I try to capture at 720x480, I get half of my frames dropped. I can capture at 352x480 and it captures great. I have not tried to go any further than capturing and editing now. Can someone help me with this? My setup:

700mhz, 60GB dedicated hard drive for video capture (7200 rpms), 128MB memory, Windows 98SE.

Thanks in advance...
