They have those under "PureVideo" support.

More info is at : http://www.nvidia.com/object/purevideo_hd_faq.html

I've successfully watched SVT HD (Swedish HDTV test channel, 20Mbit
H.264) on my MythTV setup, which uses an Intel Core 2 Duo E6420. Some
tearing occurs but playback is reasonably smooth at about 90-95% CPU
utilization.

Believe it - you're going to need at least an E6600 for completely
smooth HDTV playback until someone either optimizes the MPEG4 codecs or
we get GPU accelerated MPEG4 decode.
