Gunblade, I'm not sure Cheesy's answered your question. You asked how you can find out whether a DVD rip has all the movies etc - is it incomplete?

As I've explained, a DVD rip is incopmplete and it is difficult (not impossible) to find out what's missing by knowing the contents of the DVD version and compating it with the rip. Smaller files mean a downsample; missing files mean missing files.
