Different problem, the fix was for PVR-350. You seem to have a huge load
with VBI handling. Turn off the VBI support in MythTV and I suspect the
problem will go away. Do you have a fast or slow CPU? Can you provide
the IVTV INIT messages?
Hans
I'm seeing the same thing, only for me it started with 0.4.8 :
I have a 150 and a 350. Switching inputs doesn't change the high load on the
machine (the picture really stutters at first, and then becomes totally
unresponsive)
I'm running mythtv 0.20 -fixes from svn, on a sempron 2500+ with 512meg ram
with an Asrock Mainboard (with sis chip set). the modules get loaded without
any options.
The dmesg with VBI enabled is below:
