Well, you haven't stated what brand of media you are using. Also Bios v1.3 is out, upgrade to that as well. Seems like your ground connection, and Bios/DSP clips are installed correctly.
I have the EZI Pro with ToxicOS v0.3 in my NTSC v9, and have not had any problems with game backups. I only burn with DVD Decrypter @ 4x onto Ridata G04 and Taiyo Yuden DVD-R's.
Good Luck
