I concur.

A big plus. Also gives a pretty certain guarantee that audio and video will be 
perfectly synchronized.

Incorrect. mpeg4 has a much higher compression ratio than mpeg2, so this 
depends greatly on the settings you use. For the same resolution and 
approximate quality settings, mpeg4 compression with a bttv card will result 
in much smaller files. But of course, you can also transcode your mpeg2 
PVR-x50 captures to mpeg4 to save space.

Definitely a big plus if you're short on CPU.
