The big thing is digital TV, if you are recieving digital then the tuner
just spits grabs the 2-12mbytes of data a second out of the air and myth
sticks it on disk. Mythbackend on my 2ghz core2 server uses about 6% of
one CPU when its recording 3 shows. Watching a HD show uses about 60%,
commercial flagging uses around 70%, its getting a little busy when its
commercial flagging 2 shows and we are watching a 3rd but other than the
hard drive light being "on" the only way to tell by is running top.

We have our commercial flagging running while its recording so we don't
need to manually time skip ;->

That should be fine for standard definition but its borderline for HD i
think.

Intel onboard graphics work well and the intel driver is open source so
it comes with most distro's out of the box.
There are a few motherboards out there with intel onboard video and HDMI
outputs which make life easy.
