I err'd when I wrote the above as I actually found 2 DVD's in the drawer and the one I used was an off-brand from "Melody Group" here in Taiwan and blanking worked. 

The Philips brand DVD+RW does *not* support the "blank" option when using the dvd+rw-format tool...

[egreshko at meimei ~]$ dvd+rw-format -blank=full /dev/sr0
* BD/DVD±RW/-RAM format utility by <appro at fy.chalmers.se>, version 7.1.
* 4.7GB DVD+RW media detected.
- illegal command-line option for this media.
- you have the option to re-run dvd+rw-format with:
  -lead-out  to elicit lead-out relocation for better
             DVD-ROM compatibility, data is not affected;
  -force     to enforce new format (not recommended)
             and wipe the data.

But, if using cdrecord -v blank=all it will proceed....but I killed it before it started to wipe the disk since I found I wanted to keep the movie that was on it.  :-) :-)
