I'm using the ATI 550 analog tuner card on Windows XP for TV and FM radio channels.
With NPVR I can tune TV channels correctly and switch from TV to FM channel correctly.
Once tuned an FM channel, the tuner remains in FM mode if I go back to a TV channel and keeps tuned on the last tuned FM channel.
I can only switch back to TV mode using other software like Chris Tweak, going to the GUI of the tuner.
I don't have this problem with other PVR software so I suppose it's a bug in NPVR.
I hope you can reproduce and fix it.
