Hello there,

   i am investigating the problem reported as debain bug 
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=615978.

   In short, growisofs reports the wrong capacity when burning 
multisession bd-r media.

   While readin source (growisofs_mmc.cpp), if found that the variable 
bdr_plus_pow is set if the drive is captable to write pseudo overwrite 
(282) but bdr_plus_pow is used later (line 414) to indicate the media is 
used in pow mode.

   So the correct fix would be to ask if the media is used as pow media 
(0x51 READ DISC INFORMATION) before to decide if to use blocks already 
written or not.

   Right ?

   regards,

     michael
