If you tell it to transcode, it will.  It won't be realtime, though.

No, there isn't.  The decoder on the -350 isn't capable of decoding hdtv - it 
can't handle anything more than 480i (or standard pal), and it can't decode 
ac-3 audio - and will ignore anything but the first audio stream, so if 
that's the ac3 stream (which is standard), you won't get any audio at all.
