cat /dev/video0 will include the audio - PVR-x50 cards produce complete mpeg
streams (probably the dev node should be called /dev/mpeg0 or something). No

No, the composite input just bypassed the tuner. There's only one video
capture chip on the card so it can only capture from either the tuner or one
