DVDRECORD isn't working. Toshiba SDR-5002

[Jim Lynch]

I've attached the complete error message and other info to this message. 
I searched the net for solutions and tried the following at the 
suggestion of some of the solutions.
I turned off automounter in case it was tring to read the drive.
I upgraded the kernel to 2.4.22.
One suggesion was to turn off DMA, but I don't know how to do that.

I'm running a fairly plain woody install on a 600 mhz pentium system. 
The resulting DVD (when I actually tried to cut a disk) had the 
directory structure written to it, but no data.  That is, when I mounted 
it, ls showed the files but when I tried to access one of the files I 
got errors.  I'm using generic DVD-R media.  One of the reasons I bought 
this drive is because it didn't require certified DVDs.

Can anyone help?  If not, can anyone suggest where I might go to ask for 
additional help?

Thanks,
Jim.
