I have been running XBMC on Arch linux for a long time with no issues.

I just upgraded to Gotham and Standard definition videos now are very slow. i.e. play 1 second then pause then 1 second again. However my HD video works perfectly.

I have an ATI RADEON HD 3800 series card. The problem is the same using the Catalyst or open source and never happened on frodo so I guess this must be an issues with xbmc itself. I have tried lots of different setting to no avail. Any help would be much appreciated.

Works for me. Cannot see your Debug Log

Here is my log trying to play a video that ran very slowly.:

Your audio is not configured correctly. Set your speakers to 2.0 and retry.

That is interesting. It does fix it but I have 3.1 speakers so I would want it to be set to 3.1 normally. Am I doing something wrong?

AH! I left it to 3.1 but turned off stereo upmix. that seemed to work. Seems an odd thing to make it run slow though.
