[mythtv-users] Here we go again (LiveTV lag idea)...

 	Not to get in a flame war again, but I'd like some developer 
comments on this idea.  There's been a thread on the ivtv-devel list about 
the YUV bypass part of the ivtv driver, and it got me thinking of a good 
use for it.

 	For those who still find themselves watching LiveTV, the channel 
changing pause and CPU requirements (especially for bttv-based capture 
cards) is a rather significant penalty.  I realize it's easier to play the 
ringbuffer that's being recorded, but how tough would it be to play the 
raw YUV data via an Xv overlay in LiveTV if it's truly live?  When 
paused/FF/RW'd MythTV would have to switch to playing the ringbuffer 

 	Just a thought... don't shoot the messenger... :)
