[mythtv-users] slow channel browser

Okay, i've searched the lists, and can't figure out whats up.. Ever 
since I switched to a PVR-250, the channel browser (o from live tv) is 
really really slow.  Even now with both a PVR-250 and an ATI TV Wonder 
VE the problem still exists.

I have pruned a number of channels out of my .mythtv/*.xmltv files and 
purged the database acoordingly.  I have enabled slow query logging and 
even tested many of the queries used by mythtv to check for slowness.. 
None take longer than 0.01 seconds.  The problem does not appear to be 
mysql.    My DB contains 2 inputs, 243 channels, and 57522 programs.

The pauses are often 1-2 seconds between hitting up/down and getting the 
next channel.  The video playback slows down/stops during this pause, 
then catches up afterwards.

I am currently running 0.11 as CVS was causing me all sorts of grief.

Any ideas where to look for the cause of the slowness?  The channel 
browser mode is pretty much useless because of this.
