Hello Mike,

Bear in mind that most cards that have what you would consider
"multiple inputs" actually only have a single video decoder.  So for a
card that has an analog tuner, s-video, and composite input, you can
only capture on one of those at a time (this is the way the hardware
is designed and is not specific to Linux).

There aren't many cards which have multiple video decoders, as they
are typically targeted at surveillance DVRs.  You can look at the
HVR-2250 which has two ports, or the Hauppauge ImpactVCB, which has
three or four composite inputs).  Both of these should work under
Linux (although the HVR-2250 analog support is brand new and probably
still has some issues).
