[mythtv] OSD Program Guide with Unichrome & Deinterlacing

hi, i've got a CVS build (pre Big DVB update) running on 2.6.9 (epia 
patches) with Unichrome and Xorg. 

If i turn on deinterlacing (which i understand only Bob is supported on 
XvMC_VLD?) then the playback is smooth. However if i fire up the program 
guide through the OSD, the things fall apart:
 - Program guide takes about 30 seconds to load
 - Load average creeps to about 2.0 - 3.0
 - mythbackend starts prebuffering
When i exit the OSD/Program guide, the Load average continues to rise up 
towards 5.0 (!), with more backend prebuffering then i care to count. The 
only thing in the mythbackend logs is endless prebuffering 

eventually after about 4-5 minutes, the thing settles down again. 

But if i turn deinterlacing off, then everything works perfectly. The 
OSD/Program guide is fast, no prebuffering, no CPU climb, etc.
