[mythtv] Video playback problems

[Yan-Fa Li]

Ugh a VIA KT400 based board.  I really dislike VIA, I stopped using them 
some time ago.  Every VIA based board I've ever used has had PCI 
problems.  VIA has a number of known problems with their PCI 
implementation, search google for VIA and Sound Blaster Live and you'll 
see what I'm talking about.  What kernel version are you running ?

If you can dump that sucker ASAP on Ebay and buy yourself an nice NForce 
2 based board and just move all the components over.  ECS makes a good 
inexpensive one (N2U400-A) which can be purchased for less than $50 in 
the US.  Look for the separate 12V CPU connector.  Quality AMD boards 
have separate 12V CPU rails. NVIDIA boards are smooth as butter with a 
post 2.4.27 kernel.  Kernels before that will lock up under heavy I/O.
