Video capture and dvd burning for linux?

[scott at ehrlichtronics.com (Scott Ehrlich)]

I have an ADS Tech USB 701 box connected to a 1 Gig P3 with 384 Meg RAM
with a DVD recorder.   I'm trying to capture composite video from a VHS
tape.   The setup is VCR > ADS box via RCA plugs > PC via USB 2.0.

Using XP Pro, the included Ulead Videostudio 8 program loses track of the
capture, as it takes up the full cpu cycles and gets overloaded.

My budget won't allow for a new PC.

What are my possible Linux options for capture via USB, editing captured
video as needed, and burning to DVD?

Thanks.

Scott
