I've tried following the directions in the handbook, but I always end up 
looking at :-( and :-[ lines in growisofs.

I've tried putting my DVD-rws in Restricted Overwrite mode, but it 
doesn't work either.  After it is formatted I can write once, but 
subsequent writes return:

Executing 'mkisofs -R -J -f /tmp/burndvd/ | builtin_dd of=/dev/pass4 
obs=32k seek=0'
mkisofs: Warning: -follow-links does not always work correctly; be careful.
/dev/pass4: "Current Write Speed" is 2.0x1385KBps.
:-[ WRITE at LBA=0h failed with SK=5h/ASC=21h/ACQ=02h]: Invalid argument
:-( write failed: Invalid argument

mediainfo claims that the DVD is in Restricted Overwrite mode:

Maybe I'm reading the page incorrectly, but it seems to suggest that you 
don't need to do any sort of "blanking" operation in Restricted 
Overwrite mode, just start a new session to restart the disc.  Is this 
incorrect?

I am using the following command to burn the discs:
growisofs -R -J -f -Z /dev/cd2 burndir

I generally don't want to append data to the DVD-RWs, but rather 
overwrite them.

My current procedure is to burn the DVDs as above and use
burncd -f /dev/acd2 format dvd-rw
to reset the discs (dvd+rw-format refuses to do it since the discs are 
already formatted), but that takes forever and I have to Ctrl-C it once 
the lights on the drive stop flashing (it never exits otherwise).
