What about playing back the DVD2One output files from the HD? Does it play OK? Or does the problem only crop up with burning?
I've got SP: BLU (ie, the Movie) but am awaiting more media. I guess I could try a -RW tho.
I haven't found anything like this lately with my usual methods (DVD Decrypter to rip and ImgTool to burn). I don't have Grease, but I'm sure I have one or two other Paramount titles.
OK, I just looked at my SP: BLU. It is a DVD5! You should not even be using DVD2One to process this movie, there is no need to as it is a DVD5 and under 4.7GB (it's under 4GB in fact).
Use DVD Decrypter to dump the movie to your HD in ISO mode and then use the same program to write the ISO to your DVD burber. Voila. A perfect 1:1 copy.
