i've been messing around with this a lot lately on my PVR-500 (essentially 2
pvr 150's). As Chad said, you'll need to run myth-setup again. Under
"Video Cards" change your card's (/dev/video1) default input to S-Video or
Composite. Then under the "Input" section, make sure you have correctly
mapped your "Video Source" to your desired input. It will probably look
something like :
/dev/video1 -> S-Video -> <Name of Video Source>
/dev/video1 -> Composite -> <Name of Video Source>
if you don't have the input mapped to a source, it won't appear as an input
in MythTV. The mistake i kept making was i'd have the default input set to
something other than what i had the input mapped to, which would just leave
me with an unselectable input or just a blank screen (depending on the
setup). Hope this helps!
