Hmm. Well, if the player hardware seems OK, and it works in 1.03, my only suggestion is to stay at 1.03 and see if the problem goes away when the next public beta is released. There were a lot of bug fixes since 2.0b3, perhaps it will be fine when you can get your hands on that version.

If you still have trouble with the next public beta, please post that information so they can narrow it down. Otherwise, perhaps the empeg guys can offer a suggestion.
