Hello, I just got the Rush in Rio concert DVD and have noticed two technical problems with it. One, during the "intermission" where the animation begins and plays, the disk starts to "stick", then about 2 seconds into the animation itself it completely freezes. To get it going again I have to hit FF. I have a Pioneer DVD player (DVD0525) that is about 3 years old now. I also tried it on a newer Philips and it was better but not perfect. Secondly, the disk won't play at all on my iMAC. It doesn't even seem to recognize it. Any thoughts or suggestions? Thanks!
