Not the whole TS, only pre-selected PIDs. The recorded format is still a
transport stream though. Filtering is done in the DVB hardware.

Yep.

Hard to answer. MPEG layer 1/2 audio (stereo only): yes. You can put the 
AC3 PID in the channel settings and I think it'll be recording, but AC3
playback from DVB isn't working, AFAICT.

Nope.
