Informative Technical DVD Site?
 

Does anyone know where I can get a decent listing of technical specs about DVD's? Specifically, I'm looking for a list of titles that are:

Double Sided/Single Layer
Double Sided/Double Layer
Single Sided/Single Layer
Single Sided/Double Layer
Titles with Parental Lock
Karaoke DVD's
Pal Titles

I briefly browsed these forums and didn't find any threads pertaining to these, so I am asking this community if they know where I can find this information. Any help on these tieles would be greatly appreciated, as I need all of these and more for test plans at work.

I haven't checked all of the criteria you are asking about, but I'm a big believer in the Widescreen Review Advanced Search engine:

http://db2.widescreenreview.com/dvdr...rch2.htm&-view

Note: This only searches through titles they have reviewed and not all that are in existence. They only review DVDs that are Region 1 widescreen movies. (No TV shows, etc.)
