The fact that you see "failed to locate "Quick format" descriptor" alone 
most likely means that your media is poorly supported by your firmware. 
Then "3/11/05 L-EC UNCORRECTABLE ERROR" doesn't make much sense 
either... What media is it anyway (see dvd+rw-mediainfo output for Media 
ID)? Poor media support manifests itself in most bizarre ways. There 
were reports that DVD-RW media acts as write-once, -twice or three 
times. In other workds I'd really recommend to test other media brands, 
preferably explicitly recommended by unit manufacturer, before drawing 
final conclusions. A.
