No H.264 yet (although we are working on a 6th generation chip for that).
The MPEG-4 bullet refers to part 2 and specifically DivX. Although you
don't hear much about DivX in the US, it's very popular in Europe where
folks have DRM equipped players and download legitimate DivX content
for them.

HD video will be rescaled to SD resolution for recording to DVD. The digital
rescale should look a bit better than an analog S-Video connection.

It's up to our customers to decide which tuner and ATSC demodulator
they use. Our in-house development platforms are using the Micronas
DRX3942H demodulator (and yes, this device is rectangular in a 128 pin
PMQFP package).
