I have a Pinnacle dvc-80 gadget that takes output from a vcr and into

wondering if I can make it work in Linux. I need software to do the
capturing.

I load the module for v4l and in dmesg I see that the device is found
and registered:

USBVision[1]: registered USBVision Video device /dev/video1 [v4l2]
USBVision[1]: registered USBVision VBI device /dev/vbi1 [v4l2] (Not
Working Yet!)
usbcore: registered new interface driver usbvision


I am guessing that sets me up to do video capture, but i can't find
software that can do the capture on USB.  In kino, it seems to insist
that only firewire can be used.

If you can advise me of a way to capture this video input. I gather
the input should be stored as avi or mpg in order to fit my goal,
which is to write it on a DVD.

The candidates are ffmpeg and xawtv. I would definitely try xawtv first, since you can play with the settings until you actually get a picture and know what you need. At that point you can record with xawtv, creating an avi file. Start xawtv with the "-geometry 640x480" option for a TV size capture, or use something smaller to limit the file size. You can then use ffmpeg to convert to other formats as needed.

The stuff I use to capture can take analog, digital, or S-video input, using L+R or digital audio.

If you just start xawtv it will probably figure out your hardware well enough to get a picture, diddle from there.
