true true, but at the same time its given Myth a lot of powerful
features that make it better than TiVo. What I find amazing is that
Myth is able to do all that with very little resources needed. What
Myth needs (and I guess has it with the PVR350 for SD) is a dedicated
video decoding processor like the TiVo has.

so was mine until I decided 3 HD tuners with a software RAID5 array
was all going to be handled by my fe/be machine. Now if I'm recording
3 HD shows mythbackend uses something like 30% CPU alone, not quite
enough to watch a 1080i show without XVMC. With nothing recording I
can watch 1080i with about 80% cpu usage.

Now I need to decide if building a dedicated be or upgrading the CPU
is the best way to go. I've got a spare Athlon 1800+ mobo with ram and
a video card that I can use, I can even upgrade the cpu to I think an
Athlon 2700+, so I'd need a case and a good power supply. Which I may
end up doing considerin the addition of 2 new frontends soon...
