[mythtv-users] Constant Video stalls/lockups - looking for suggestions

[Bruce Nordstrand]

Hi all

I am having a bit of trouble with video playback - both TV (PAL SD) and 
videos of various types (avi, mpg etc). I am running MythBuntu with .021 
on a 1Ghz Pentium III / 512Mb ram / FX5200. I was running 7.10 and 
upgraded last night to Hardy to see if the problem would go away.

Playing *anything* will result in the video freezing for up to 30 secs 
and this happens randomly and sometimes more than once. Videos are on a 
network share via NFS and do the same whatever I use as the player 
Internal, Xine, MPlayer. It doesn't matter if there is anything 
recording or not - this machine is a combined frontend/backend. This 
makes it real hard to watch things like Buffy and Dr Who!!! :)

Here's the kicker.... I installed (compiled) XBoxMediacenter for Linux 
on this machine just to take a look. Somehow, it plays anything and 
everything perfectly - no jumping, no freezes - just clean video playback.

My question is: What should I be looking into to get MythFrontEnd 
playing just like XBoxMediacenter?  I must say that prior to installing 
MythBuntu I had standard Ubuntu with a custom compiled Myth and did not 
have these problems. I tried out Mythbuntu for the ease of it all after 
going down a different track so to speak. I know it can't be the machine 
because of XBMC playing fine so it has to be some settings somewhere.

Any and all help appreciated.

Cheers
Bruce
