My player doesn't seem to like some of my discs. The newest one is CSI: Season 6 disc 4. Every time I try to play one of the episodes on it, it scans through the chapters, never plays them and tends to go back to the menu. It also happens with Lost: Season 1 disc 1 and The Santa Clause. All of the discs play fine in other players. I have a Toshiba SD-3805. Is it just a software problem, and if it is, can I fix it?
