okay so a bit more information before I spend several more days doing a re-encode

Playing the disc back normally appears to be problem free with the exception that the timer/counter on the DVD player doesn't advance every second. I can live with that if i have to.

But skipping chapters is what introduces the problem i described earlier where it'll play 3-4 seconds, skip back, play those same 3-4 seconds again followed by the next 3-4 seconds, and repeat ad nauseum.

Skimming thru the movie with fast-forward results in a frozen frame when hitting play.

I did not create a menu, just the base DVD.

Any ideas as to what might be causing this strange behavior? Thanks in advance...
