I have a Panasonic F85. After playing about 150 disks on this player (which I've owned for two months) I have not notices any cases where the picture has frozen and I could not fast-forward through to get the picture moving. That is, until yesterday, while watching the TokyoPop disk VERSUS. At exactly 58 minutes into the film, the picture just freezes. The only thing I can do to get past it is to enter the time 0:58:04 into the player - jumping the film just enough seconds ahead to get out of this log jam. Either that or jumping to the next chapter and rewinding to as close to the frozen moment as I can without getting stuck again. What makes this happen on an otherwise healthy DVD player?
