XMS 750 DVD standalone wont play my dvds..

[Maxwellbest]

Title says it all.

I capture video from my digital video camera
I edit in Ulead Video studio 7 se
I convert to mpeg with TMgenc 2.5
I author and burn with TMGenc DVD Author

I use Princo 1-4 DVD-R for media

The final DVD will play on a Playstation 2
Will play on my computer via my LG DVD burner

BUT it will not load on my XMS DVD standalone player. Most odd, because it has normally played anything I have thrown at ie home burnt svcds etc. And prior to it not accepting the latest batch, it accepted the dvds authored according to the same process as outlined above. It has just decided not to accept the latest batch, for whatever reason.I have searched most forums but can not find any one with a similar experience with this dvd player. Any help would be most appreciated.

Cheers

A bit more detail on my previous post. It seems by DVD Player will play DVDs authored by TMP BUT only if the DVDs comprise no more than one chapter. Ie it will not play dvds with multiple chapters. Very flaky. But anyhelp on this most appreciated...
