Recently purchased the Panasonic dmr-e55. Successfully recorded onto the first DVD-R that I put in. Was able to record from TV signal as well as from a VHS deck. But that is it! Each time I try to create another recording on another disk, the machine goes into Self Check mode and after a while says "Bye". It then ejects the disk and says that the media is bad. I cannot make anymore recordings! The machine does the same for any new DVD-R disk that I try to use. I called the Panasonic 800 service number. The rep said that the machine wasn't bad and was doing what it should do. He claimed the media was bad and said that I should use disks made by Panasonic, Pioneer, Fuji, Verbaitim or Sony. I'm using Fuji disks! He also said that the machine writes a 1X so I should not buy disks that are rate higher (4X, 8X, etc). I find this hard to believe! I've been writing to CD and DVD on my PC and have never had problems with bad media. I'm going to return the machine to the store where I bought it but my question is should I simply exchange it for another DMR-E55 and hope the new one works better? Or should I get a different make? I read good ratings for the Panasonic unit... I wish it would work!
