But whenever I record hi-def channels (remembering again that recording them merely throws them at the disk, and doesn't do any encoding/decoding), I then transcode them in non-realitme AFTER they are recorded (and again, at low CPU priority), which also resizes the frames to a lower resolution, which then lets me watch "hi-def" shows (I use the quotes there because they are downscaled from their original hi-def resolutions, and are no longer truly hi-def).  Now that Channel 10 and others here in Australia are showing different content on their hi-def channels to their standard-def channels, it's nice to have the freedom to watch them without needing a hi-def TV nor fast computer to decode them.

I am running Mythtv on an AMD Athlon 2600+ and it can record 2 channels
while playing back a recording without issue.
It can record and playback one hi-def channel, but the playback gets a
bit jumpy if another recording starts at the sametime (most likely due
to slow harddisk rather than cpu as the cpu usage stays pretty low)  The
jumpiness can probably be got around by using multiple disks to store
the recordings, or just faster disks :-)
