[mythtv] slow program guide in .21

[Lance Buttars]

The program guide is really slow in myth .21

I can fix the guide issue by using the mythfronted -v all command but if 
I do that the video play back is choppy.

system hardware is 3.0 ghz 4 gig ram intel core duo.


This only happens when you try to view the guide and the tv at the same 
time.  The guide works if you go into it to from schedule recordings.

is there any news on this issue ?

Thank you.
