I checked a few Warner titles so here You go:
300(non combo,Germany): perfect
V For Vendetta(UK): perfect
The Prestige(UK): perfect
Terminator 3(US):It was a sealed copy but I've opened It for checking & It's working without probs so "no problemo".

16 Blocks (UK): perfect
Alexander Revisited(US):I've checked 1st& 2nd Discs also.everythings fine
Enter The Dragon(US): perfect
House Of Wax(UK): perfect
Troy:Extended Cut (US): perfect
Harry Potter 1(UK): Perfect
Harry Potter 2(UK): Perfect
Harry Potter 3(US): Perfect
Harry Potter 4(UK): Perfect
Harry Potter 5(non combo,Australia): Perfect
Swordfish(US): perfect
I found 2 problematic Warner titles only:Blood Diamond (totally unreadable) and The Last Samurai (it has layer break/freezing problem but my X360 HD Drive read It without errors)
I checked a few Universal & Paramount titles also but I didn't have any problems with them.

Maybe this is a small "favor" (or a gift ?) from Warner to the remain HD DVD fans.
