what do you mean to try CDSpeed without burning the image?
the specs should be enough - P4 3.0Ghz, 512 ram, 80gb 8mb WD.. when I try to copy the file back it copies fast enough (32mb/s).
when i do quality scan of burned discs it looks great - flat, low errors, so it shouldnt be AOPC (at least doesnt need to).
it all looks really fishy to me - same prob with different discs, different firmwares..
i guess i could try burning in Nero to check if buffer keeps full during all burn but then I cant see the speed graph shrug
