I actually believe that the problem is with the bltfill calls i added in 0.17 of mythtv. Occassionaly these seem to fail completely and the firmware never does the blt fill.
I spent ages looking at this recently and came to the conclusion that the firmware/card is going wrong sometimes. The latest patch i submitted to the myth dev list no longer does blt fill to clear the screen and this seems to be stable for the people who have tried it. So you could either try the patch i sent to the dev list about 3 weeks ago (labeled second attempt) or in libs/mythtv/videout_ivtv.cpp make the check for the version just before the BLT_FILL ioctl fail so it does the PREP_FRAME instead. If you try this please let me know if it helps.
