[mythtv-users] ivtv-0.1.9 and latest mythtv

Hi,

	I have played further with a post 0-13 mythtv. and the layest mythtv (checked 
out around noon EST today)..

	Running locally on the machine with the PVR-350 everything works file, with 
minimal CPU load.

	Xdisplaying back mythfrontend with the tv going to the fb device works, but 
myth uses about 30%cpu (duron 1200) and there is a lot of network traffic, I 
cant understand why as the display is blank, everything is going out the card 
to the TV.

	Previously I was ssh'ing into the machine and using the ssh display to come 
back, now I am straight Xdisplaying back (so no encription and lower overall 
CPU load).

	I was locking up after about 30seconds of pre recorded showing,Now it can 
handle about 30 minutes. I assume this is due to the lower overall CPU load 
(no ssh).

	Watching live TV uses mimimal CPU however I do it.

	Everything is fine on 0.13.

	Any ideas ?

	Thanks,

		Stuart
