growisofs 5.21, Plextor PX-708A 1.09

Hi!

Eversince upgrading the 708 from firmware 1.07 to 1.09, I get two "ioctl 
ILLEGAL REQUEST" error messages (kernel 2.4.27) while writing a DVD (verbatim 
+R 4x or +RW 4x)

With the new firmware the 708 seems to be unable to produce error free DVDs 
with "older" Verbatim +R 4x DVDs (43213). No write errors from growisofs, but 
read errors in files in the last 1/4 of the DVD.

Has anybody else seen error message or errors like these with the new 
firmware?

Thanks!
