It's not that easy.
The signal from plain VCRs (NTSC, PAL or SECAM) is too dirty. You will run into transfer issues. Even TBC often cannot fix the messy output. Those were analog, pre-digital, for connecting to a TV. Only broadcasters had to worry about signals, as the analog TVs ignored many flaws.
SECAM-L is also the most difficult VHS format to work with. You not only need SECAM playback, but the output is SECAM as well, meaning that PAL wiring won't work. You need French SCART. And a card that is SECAM-aware (and note that
VirtualDub may lie to you). Many capture cards do not support SECAM at all -- only PAL and NTSC.
FYI, the AIWA, JVC and Samsung are Panasonic rebadges. And I'm not aware of anybody else making a multi-format deck aside from Panasonic. Those are regular VHS, but not consumer grade. Those have a lot of flaws, too. JVC does have some rarer SECAM S-VHS decks, but I'm not sure about L. In 15 years, I've had maybe a dozen SECAM tapes, and use the Samsung 5000W, which doesn't support L.
SECAM is like 99% PAL. In fact, the internal of SECAM VCRs are just PAL VCRs, with a converter for the color. But that 1% is enough to cause you grief.
Good luck.
