NEO2.5 DVD-R Issue

[fenston1]

Just installed my first NEO2.5... Seemed to be easy enough (I'm getting used to doing all of the soldering now!) All originals work fine, all PS2 CDR backups work fine, and all PSX CDR backups work fine. DVD-R backups (I finally recieved my Pioneer DVR-A03, thanks for the advice Charlie!) don't want to boot. Someone said it was due to the version of GS (v2.01). I was informed I must use GS v1.93 to have it work. Anyone have any input? As always, thanks in advance.
