Hi faginuk
No sorry i still have this problem, infact all the programs seem to do this. only suggestion to remedy the situation i know of at moment is to convert the mpeg using conversion software into a different size but that can take a while. more excellent info available here

just look under convert or guides etc on main menu page on the left and that will bring up a section on it. Also a good site to check dvd pplayer compatibilities to see what it supports. An excellent program would be "TMPGEnc" which is probably one of the best. You can set it up to convert your mpeg to a different Aspect Ratio or file type. Just convert for a few seconds to see results then when happy convert the whole file but it can take a long time to do depending on settings perhaps even 10 to 20 hours if converting to mpeg 2 etc. But i recon there must be a way to fix this problem without having to convert the mpeg, i think there must be a codec somewhere out there that works with dvb software to fix this problem but i havent really looked enough to find it as i am too busy just trying to get a decent picture without the jerkyness any blockyness at the moment and i think the problem is my processor just is not up to it either.
