Anyone have problems playing DVD movies on their combo equipped iBook? I just bought a new 12" 900mhz combo iBook, and so far am quite happy with it. However, while watching a DVD, about half way through, the movie started skipping/even stopping all together, as if it was dirty or scratched. Close inspection showed that wasn't the case. I probably didn't have the iBook situated well enough to dissipate the heat, as the bottom of the iBook was very warm (much more than its normal warm self, as I realize that is where the heat is dissipated from). After moving the iBook to a location that would dissipate the heat better, the same DVD played through its entirety just fine. Joe
