    Not really bad but you can do better [​IMG]

    What speed did you use to burn your media ?

    8x, if I do 4x they don't work
    They are very cheap DVD's (I bought Expensive ones first they didn't work then bought 100 Cheap DVD's which where said to work and they do)
    Mediacode = RITEKF1

    Unacceptable PI at the beginning. The spike near the end could just be a drive error.

    So it's not your Media, because I have exactly the same mediacode and I have with Mario kart Wii

    Oh, well I got a budget Samsung DVD Burner so that explains it I guess
    But does that mean the burner is also providing a badder quality or is it just the reading that show bad quality

    I've just swapped back to -r after getting a faulty batch of Verbatim +r. I'm now getting quality ratings of 98% each time on a Piodata 108DX.

    That said and done, it's always seemed to vary heavily depending on where the ISO was from. GC games i've backed up myself on +r have always been in the high 90s, but Mario Galaxy always got about 40% - tried burning 3 times, never had a DRE or problem reading the disks though?

    I've read that sometime a low quality metric (70%) may be acceptable in certain situations. It really depends on how the errors are "spread out" across the disc. From what I understand, if there is enough space between errors, then the data correction algorithms have enough data to recreate the bad parts.

    Think of it like this. Suppose you have cards numbered 0 and 1. You know that 3 cards in a row always add up to an even number (the 3rd card is the checksum). One error (of the 3) is detectable, but 2 are not. This is a hugely oversimplified example of how data correction works, but you get the idea.
