[mythtv-users] HD playback h264 crashes, or stutters

[Paul]

Now this is not life or death but I currently have two problems with
this front-end I am playing with.

The motherboard is an ASrock NF6 with 2GB ram, and an AMD Athlon x2
3800, tried both on board 6000, and also PCIe 6800, am aware I have
problems with the audio, so currently set to disabled in Myth. Tried
numerous profiles with varying degree's of success, but all pause at
some stage. Mythbuntu 8.10 no patches applied.

Here is my front-end log, any pointers ?
