I have had a DMR-E50 for a few months now and have been very happy with it. I recently got a Panasonic 9581 burner for my PC and when I tried to copy some files from a disk to watch through the E50 I got a message saying something like "Incompatible Disk". The disk was done by a friend of mine onto a dvd-rw disk and I copied the contents onto a RAM disk. When this didn't work I copied the contents to the hard disk and then used Nero to burn to a -r disk, again the same message. I have been using the same media in the E50 so I know it works fine. What am I doing wrong? I can play the files on the PC but not on the E50. I had wanted to be able to record onto a RAM disk and then if I wanted to keep it to copy to -r using the PC. Is this possible or not? Thanks in advance for any answers. Andy.
