[mythtv-users] PVR-350 displays OSD but not video - .17 apt-getupgrade

[John Harvey]

I believe this is caused by blt_fill code in the firmware crashing
occasionally. I was working on some changes and managed to get to a point
where this was very reproducible (though not every time).

In libs/libmythtv/videout_ivtv.cpp in the function ClearOSD() there is some
code that looks something like 
  if (version > 0x00000????)
{
	 Clear using old method
} else
{
	Clear using BLTFILL;
}

If you change this so it always uses the old method you might find it fixes
the problem. Easiest way is to just make the number being compared against
larger termporarily.
I spent ages looking at this and came to the conclusion that the firmware is
broken in some way or there is a horrible interaction with the dma code.
