I'm in Australia, with DVB-T PAL (so 50hz) on a 60hz native res LCD
(samsung 40" 1366x768). What works for me:
-VSYNC OFFFF!! (you MAY get tearing, but I don't, and THIS is what
causes your jitter)
-bob deint (make sure your refresh is set at least at 60, debug to
make sure it's operating at 2x framerate)
The downside is that any OSD that has transparency will "bob." I get
over it. If you can't, use OSDs without transparency.
