formatting a DVD+RW

[Xian]

I am trying to format a DVD+RW as I gather this kind of DVD needs. I tried 
growisofs and it told me:

 * DVD±RW/-RAM format utility by <appro at fy.chalmers.se>, version 4.10.
 :-( unable to open("/dev/acd0"): Inappropriate ioctl for device

I then tried

 burncd format dvd+rw

but that that just sat there for a few hours and did nothing. It didn't do any 
progress reporting like the man page said.

I'm stumped now. Does anyone have any ideas?
Thanks in advance.
