I have a few DVD-discs that dont play or do play but play jerky, jumps, and shows large fields of bad picture. Sometimes it look like som fields are faster than outhers.
this is only a problem on my standalone, a Hitachi 515E. PLaying them on my pioneer dvdrom gives no problem.

the discs are ntsc and the standalone playes them in quasiPAL. maby the convertion is bad?

what to do, what to do.
