- I'm afraid CpuBlit won't help with the "jittering"; this is caused by
- the fact that the screen is only being fully updated 30 times a second,
- while each field is being updated at 60 times a second. It's the same
- reason that moving objects break up on de-interlaced screens. There's
- no easy cure, unfortunately.
-
- (I read that the new Philips 100 Hz TV's which essentially have a built-in
- flicker fixer to make the TV picture look sharper actually do real-time
- analysis of the display using a custom chip to get around the "break-up"
- problem; I doubt it would be able to cope with a page of scrolling text
- though :-)
