I have used a Hauppage HVR-1110 (DVB-T and analog hybrid), with one of the TV viewer software
(xdtv?).
Connect VCR to composite in and soundcard audio in. Start the viewer, select composite in,
start the VCR, select recording options on xdtv, start recording... The main problem is the
need to be able to do real-time encoding and certain file formats limitations (for example,
avi files are limited to 4GB).
