Has anyone seen movies which are burned onto a standard dual-layer dvd9 disc and which should contain 7.x gigs of files show up in Windows 7 Explorer as containing up to 45+ gb of contents? Is this new copy protection or just a Win 7 bug? Many .vobs seem to be shadow duplicated which probably accounts for Win 7's erroneous read and listing. When I made an image (.iso or .nrg) file from the disc and then mounted it with Daemon Tools it still appeared to be 45gb.
It's a form of protection used in some commercial movie DVDs. Once the disk is decrypted with the likes of DVDFab HD Decrypter, the anomaly vanishes.
Thanks attar, Yes, ripping with anydvd to hd seems to fix it. It now reports an expected # of vobs and hence the size is in range of a DVD9.
