Hmm.... how do one knows whether the Disc bought is a real D9 or D5? Like in the GOW2 case.... many *ahem* are selling it at D9 price, but actually it could be a D5 discs only, and incomplete one some more ..

I remember reading it some where, but was not able to search back that post, where there is this software can check whether the disc is dual layered or single layered.

Anyway, can I just insert the disc in my PC's DVD-ROM and check the size? if smaller than 4.7GB then it should be D5, and if greater than 4.7GB then it should be a D9 disc?

Thanx in advance.
