Hi Quible,
I think that one more important thing was left out - - your DVD model.
Have you first searched in the
dvd-models ??
If may all turn out that your DVD model may have to be mux or something
like that before it can work.
(MPEG-2)
I have the Apex AD-1500, and I knew that it wont play 528x480 but WILL
play encodes done w/ 544x480 resolution. That's just an example. So,
do take a looksees over there (above link) and see just what your DVD
model is capable.
It may just turn out that your DVD model may not be listed. If so, (which
I doubt) then your model could be considered beta (compatibility'wise)
until kinks/issues are found and work-arounds are mades, if they can be.
