Ratchet & Clank: Up Your Arsenal Online Works?

[ToolNila]

I backed up my copy of Ratchet & Clank: Up Your Arsenal with the ps2nfo/disc ID insertor method, yet I get a DNA$ error (-864). I've made 2 back ups and both show the same error. I used:

DVD Decrypter
Ridata 4X +R
DMS3 Ver 2
V7 PS2

I looked up -864: Invalid media, e.g. using CD-R and DVD-R discs against the production server, or using manufactured discs against the development server. The back up works, but when I log onto the Internet with the disc, I get the error.

Any idea why I get the errors and what I can do to play online?

Thanks,
