Hi, is there, by any chance, support for the BenQ DW822A drive in sight? growisofs was able to write on a 4x DVD-R but the resulting disc wasn't readable even by the very same drive. Same result with 2x velocity. If not I will return this brand new drive. I'm running "Linux 2.4.22-1.2149.nptl i686 athlon i386 GNU/Linux" and "growisofs by <appro@fy.chalmers.se>, version 5.13" Thanks for your help. It is very much appreciated. Benjamin
