[G4] more about the DVR-109 and Dual Layer writing

Following up on the earlier suggested URL: http://club.cdfreaks.com/showthread.php?t=137761,
which offered a firmware updater for DVR-109's (which I just did by re-attaching mine to my PC):

=================================

Note that it does indeed mention DVD-R/+R writability and readability, but I read that all too quickly and did not see the "-R" part. 

However, after just having flashed my firmware to the new 1.50 version, I noted on my Mac System Profiler that it says "DVD-Write: -R, -RW, +R, +RW, +R DL," but nothing about -R DL.   So, I really don't know if the DVR-109 will do -R DL on my Mac.  Not that it matters much right now, though. 

Anyway, sorry if my earlier oversight has mislead anybody.
