I have a panasonic DMR ES15 that is now about 1 1/2 years old. Recently the power went out in our home for about 10 seconds, came back on, went off for about a minute then finally came back on. The DVD player was on, unfortunately. The player records fine, I just can't finalize any DVDs. It will begin but about the time it is nearly finished I get a message saying finalization failed. Any ideas short of sending it to Panasonic as to what might cause this. Other than this problem, it plays and records with no problems.
