"Could not perform start of Disc-at-once"

then the process fails
=[

any ideas?

I think your post got cut off
care to add the error dump ,and a description of what you were doing

sorry lol.

burning a DVD iso, (gamecube) doesnt even start ot burn the disk
just shows ""Could not perform start of Disc-at-once " “precess failed”

Update:
seems only mini dvds are effected, as i can burn full sized ones fine… only they dont fit in my gamecube -_-
