[mythtv] [mythtv-users] Watch Recordings is slow with SVN on my Epia

I seem to have an identical problem, but with my Epia 1Ghz Nehemiah cpu. It 
performed well for a very long time, but since 3 months or so, I see 
identical problems. 

I do not use the OpenGL painter, or the preview thumbnails or the 
live-previews on this frontend. Thumbnails are generated correctly by MythWeb 

When I skip through the "Watch Recordings" it takes several seconds, the X 
process takes 100%CPU usage during that time. I tried several things with the 
fonts, but no difference. I tried DPI(100x100) and (80x100), but that also 
makes no difference. Also different themes did not speed up anything.

Using the different verbose levels on the frontend did not show anything 

I tried profiling MythFrontend with OProfile, but it only showed some QMap 
actions that did not take much CPU.

What can I do to further debug this problem?
