I haven't noticed the difference coming into summer, I'll see what
temp the CPU is running at.  On Ubuntu what's the best utility for
tracking this info?  Funny thing is that it can be recording another
(sometimes two) channels and playback with no problems.  I've got a
raid 0 system and I've noticed that it is a lot faster in IO.

When you say it might be more stable on 32bits are you suggesting I
have to revert to a 32bit OS?  Not keen on that idea, I've spent ages
getting things the way I like them!  Will the next version of MythTv
be more stable, do I just have to be patient?
