I could have sworn that I wasn't having any luck with s-video + the
composite port for audio (I guess even though this jack is an RCA jack,
it only works for video inputs?), but s-video + the line-in port is
working just fine. Much better!

Thanks for your help! My only outstanding MythTV issue is getting Ubuntu
to work with my IR Blaster (see my other email on this just sent to the
list earlier today).

You're the best!
