screwed up = Mythtv menus unreadable due to scan lines be overlaid, one on
top of another or maybe in the wrong order. I also get vertical banding
but I can't suss out an algorithm that would describe it. I'll have a go
at taking a couple of pix tonight and put onto my web site.

interlace problem I think = not having seen an interlace problem since the
days of 405 line TV (yup, I'm that old!!) I'm guessing. I see no change to
the timing of the horizontal sync as I change displayed items but my
'scope doesn't have the resolution to see small changes in frame sync.
I'll see if I can borrow a digital 'scope from work and check the signals

Its very odd that watching direct TV, replaying a program both in Mythtv
or a video in mplayer or DVD in xine are all perfectly OK. Its just the
Mythtv menus that are "screwed up"!!
