First time here, so I hope I am asking this in the right forum. I have a Philips DVDR-75. I am getting the following error messages AFTER I make a recorded copy onto a blank TDK disk: "Disc contains unknown data". The above happened after I added the 6th Perry Mason TV story to the disk, using the M6 recorded mode (which gives me 6 hours). The Mason series only runs 42 minutes. Everything was going fine until I got near the end. This is the THIRD time this has happened in 50 disks. And all the time it was with multiple recordings from the same series. I also lost a disk with Leave it to Beaver broadcasts. Another error I have gotten is "Cannot read" after I recorded a bunch. Is my Philips over heating?? I paid $450 new. If there a better model for DVD+R's? I also use this in conjunction with a Replay 5040 model (which cuts the commercials out). Hope someone can help. PS: Anyone have a chat link for Philips Support?
