Are these commercial DVDs? Or are they "burned" DVDs?
That could be the result of an incorrect field-order setting during
the MPEG encoding process. I have also seen that effect when watching
a PAL DVD with my NTSC DVD player and NTSC TV (the DVD player does
some sort of on-the-fly conversion with that as a side effect). And I
have seen that effect after simply re-encoding a PAL video into NTSC
format with TMPGEnc.
If this is happening with commercial DVDs that are in your native
format, I wonder if it could be related to something being set for
progressive scan when it should be set for interlaced (or vice versa;
I don't know a lot about that subject).
