I'd think you should be able to playback one stream with that CPU
(assuming you're not short on ram..), as I've heard of people doing it
with less, but I don't have an HD setup to compare, so I won't swear
on it. I remember a page charting what the recommended hardware was
for the various levels (480, 720, etc)on the Mythtv site, but can't
seem to find it :(
Have you tried underscanning? see

Yes, XvMC is tricky to get working. I had to find the right
combination of Myth playback settings and xorg settings to get it
working. See http://www.mythtv.org/wiki/XvMC and whatever the
equivalent mythbuntu forum is.
A member of the mythbuntu support team showed up in the irc channel
last week, so we invited him to our next mgt. If he does come, he
might be able to help you out.

re previous comment @ xfs; Mythbuntu has likely chosen xfs as a
default because it generally does much better with large files. I
manually switched mine to xfs from ext3 and saw a noticeable
difference on certain operations (ex- deteting files)

note to others running Knoppmyth (I know a couple others are..) - the
next version, due at the end of this month, will seriously change the
distro. Since the passing of one of the BDFL's, they have decided to
regroup, base it on Arch, and change the name to LinHES.
