Video source was a VHS tape, wich was linked to Composite Video Input in my
Pinnacle PCTV. I have also a Pinnacle DC10+ , but I don't know it never worked
with VHS tapes: only with my analog videocamera's S-Video output. However, it's
rare, for me, record a video from a VHS tape, so... PCTV is OK.

This is, unfortunately, a data that is lost, because I didn't record a log...
well if for you it's so important, I can try to record that tape again, and
record lavrec Std Output with "tee"... tell me if it's so important, and I'll
do. :)
