Last night I recorded off air on my E50 using a new Panasonic DVD-R disk. This was one of the individually packed ones not in a spindle by the way. When the program had finished I pressed Stop and the machine went through the normal "closing but not finalising" process. The process didn't complete and the machine appeared to "reboot" and then a message came up on screen saying that the disk was incompatible. I tried to read the disk several times both on the E50 and on my PC but nothing comes up at all. Firstly, what happened? Secondly is there anyway that I can recover the data on the disk? I have used these disks before without any problems so this is a little disconcerting.
