i agree with the slower speeds associated with original disc. when backing up original disc i typically get speeds around 5-6 MB/s but when doing an older movie or recopy of a backup i typically get speeds of 11-15 MB/s.

now i dont know why. just assumed it was normal. if you figure something out let us know.
