In my hardware (wintv-fm), at least, demodulating the fm and tv sound is both done by the same chip - so I wouldn't expect that both could work at the same time. One possible trick comes to mind if you could use composite video - route the video sound straight to your sound card. Then install btaudio. May be able to put the audio on the card into fm mode and get its sound out of btaudio whilst the composite video sound comes through your sound card. Steve
