I have just sent my SECOND DMR-E20 in for repairs. The problem with both machines has been the same: after 6-7 months, the machine gradually refused to record on more and more DVD-R discs until, finally, it recorded on none of them, not even the three brands recommended by Panasonic for use with this machine (it's own brand, Pioneer, and TDK, all of which are quite expensive). I was able to use less expensive brands such as Ritak and Optodisc for a while, but eventually nothing worked. I was getting "U-11" error codes about 30-40 seconds into each blank disc, followed by shutdown or, worse, the machine allowed me to record all the way to the end of a disc and, when finalizing was attempted, gave me the same "U-11" followed by a "U-99" code. Extreme waste of my time and very frustrating. The machine I just turned in for repair is a replacement for my earlier one, which they could not repair. Don't know if they can fix this one, yet, either. Anyone else experience these woes?
