Some DVD's won't read on my PC at all! :sad:
I also tried them on another PC.
AnyDVD (version 126.96.36.199) reports that there is no disc in the drive (4KUS External 16x).
The strange thing is, if I put the same discs into my Home theatre at home, it works perfectly!
DVD Region+CSS Free (version 188.8.131.52) does exactly the same.
The DVDs that does not work is:
Lilo & Stitch 2
Urban Ledgends - Bloody Mary
