HI!

Using NVidia 6629 TV-out with XV for playback in mythfrontend, I get:

- 1% CPU for mythfrontend
- 40% CPU for X

But total CPU is at 80%, causing prebuffering pause every now and then
(and all the time, if I enable kernel deint in addition).

Strange is, I can't see any other process with "top", that takes the
rest of the CPU (the other 40%).

Fecora Core 2, Kernel 2.6.9, Myth 0.16.

Kernel 2.6.x has changed the way the /proc filesystem reports CPU time, such that 'top' does not see CPU time consumed by process threads of the original program.

See e.g. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=222817
(starting about halfway down) for some discussion; evidently 2.6.10
changes this behavior.
