I've read a lot of the threads in this forum trying to find an answer to this problem, but most of what I could find addressed a burnt dvd in a pc not playing in a normal dvd player. I have a different issue. I recently purchased a panasonic dvd recorder to replace my old vcr, and I have begun transfering home videos to dvd and recording tv programs. Last night I played a dvd of home movies in my pc and, although at first played fine, after a little while it froze. This happened several times, in both of my pc dvd drives. I then tried a dvd i recorded tv programs on, and experienced a similar problem when trying to select the menu while watching one of the chapters. It then froze and would not respond to anything! However, both disks appear to play fine in the original recorder!! Also, I loaned a disk to someone a few nights ago to watch, also recorded on this panasonic, and he told me this morning that it also froze at a certain point on his pc!! The only thing I can think of is perhaps the 8x media is too fast and causing errors. I don't know how to slow the dubbing down, or even what speed it records at for that matter! I am using the Panasonic DMR-E85H, and the media I am using are the Fuji 8x dvd-r and I also tried Pioneer 8x dvd-r disks, and have had the problem with each type. I burned them using the dubbing feature of the recorder, and they were all is SP mode. My pc is a compaq presario laptop, and I also tried my external dvd burner. Any comments would be most appreciated.
