Are they using H.264 for high-definition stuff? If so, a lot of
European MythTV users are going to have to spend a whole lot of money
on processors...

H.264 will be used for HD yes, also for SD, though likely that will be
on IP (telco's) and over DVB-T. On SAT i expect the combination of
DVB-S2 with H.264.
Myth will also have to learn the new types that have been approved to
signal H.264 in DVB. Currently it ignores H.264 broadcasts as non-TV
broadcasts (Yes, H.264 broadcasting has started).

P.S. DVB-S2 PCI cards haven't hit the market yet....
Dish and DirecTV are moving to H264 as well, I know they both recently sent up
satelites for using mpeg4 and many expect the switch by the end of next year.
But that just means that DISH and DirecTV will be spending a lot of
money on processors* (or, more likely, satellite customers will be
paying a lot of money for new receivers ;). Since DISH and DirecTV
don't allow dumping of the stream (i.e. via firewire), the only output
from their receivers will be RF Modulated/S-Video/Composite (for NTSC)
or Component/DVI/HDMI (for ATSC)--which means Myth will never see the
H.264, so Myth users won't need to worry. :)

*Actually, they'll probably get dedicated H.264 decoders, which will be
much cheaper than Athlon X2 4800+ processors. The 4800+ should come
close to being able to decode 1080i60 ([EMAIL PROTECTED] frames/sec (60
fields/sec)) in software in real-time, although I still don't think it
will quite make it. Maybe the 5000+ will...
