just an f.y.i.

I have had my Sony DRU500a for several months, and have always used Nero to burn cd's and dvds. To make a long story short....I have not had any problems until I upgraded to 5.5.10.35. I burned several different brands of dvds (all of which were previously burning fine with 5.5.10.28) and get no burn errors, but the discs will not play in ANYTHING including the recorder is was burned on. I have 3 different set-top boxes and 2 dvd roms. I reverted back to 5.5.10.0 and they played fine. Upgraded to 5.5.10.28 and they were fine also. This is a serious flaw that should be corrected immediately. It took me 2 days to troubleshoot this problem as I had just received some new dvds and didnt know if they were defective or not. In my time spent I burned about 9 coasters and exchanged my DRU500a for a new DRU510a until I figured out that Nero was the culprit all the time. I dont know it this is only relative to the Sony's or other burners.
