I have a Panasonic RV-31 and everytime I watch either disc of the 10 Commandments my player locks up. To make matters worse, after I turn it off it won't even eject my disc until I leave the power off for about 30 minutes to an hour. This is the only disc that I've found that does this. And it isn't a fluke thing. It always locks up after watching it for about 10 minutes no matter which scene I start from.
