I have a Dazzle USB Capture Device, and I can't use it because I can't find any good Video Capture Software. The sound lags in TVTime, and I can't get any Video Signal on XawTV. If anyone could direct me to some good software (or possibly help me fix the problem with my previous programs), I would be grateful. Thank you.

What are you looking for output?

ffmpeg and mencoder, although you generally can't watch while capturing.

MythTV

VLC

lots of options per say. My Sanyo FH1 works as a 640x480 webcam via the uvcvideo module. luvcview to setup the input parms. ffmpeg to capture although no audio and framerate gets a little off. But I can work with that via named pipes and other means. I just need some faster computers for a little elbow room.

mencoder has -audio-delay #.###

ffmpeg has -itsoffset 00:00:00.###

basically audio normally happens in realtime and video takes a while to decode / encode and a sync problem is almsot inevitable. Audio being early in most cases and to a varying degree depending on how fast or busy your computer is. Perhaps less of an issue when computers are so fast to render the gap unnoticeable, but we're not there yet. Normally 1/5th of second is typical on my systems for standard definition content. 0.200 seconds. 0.155 - 0.222 really and roughly.

I'm pretty new to all this. That being said, I can't figure out why VLC won't see the device, and I REALLY can't figure out MythTV. Is there something I have to do in the Terminal?

Kaffiene in debian has all of the ATSC scan info for setting channels. And another option for using your card.
