Since he's using VGA for Myth, he doesn't even need the S-Video
switch--just a long S-Video cable. BTW, a good S-Video cable can go 50'
(16m) without any problems.
However, I definitely agree that taking the PS2 through the encoder card
is a waste. Even if you get passthrough working in ivtv, you'll still
have to get it working in Myth (which doesn't have any support for
passthrough) or--more appropriately--in xawtv.
