unrated and directors cut dvd's...what is new?

[lordhutt]

With all the unrated and directors cuts out there...anyone know of a website that lists what is actually new or additional to these dvd's?
The dvd's are always advertised but they never say what is new...hell, it could be a lousy 5 seconds of extra footage.

They might say 'never seen before footage'...ok...a 10 second scene or many adding 10 minutes?...

A nice guide would be nice...anything like this out there?

The forums on IMDB usually detail exactly what is added in the extended cut movies.

Unrated cuts usually add a lot less back, as often it can require only the cutting of a few seconds or even a few frames to get back down to an R rating. Director's cuts can be very different to the theatrical cut, and could add an hour or more in some cases.

One decent (although incomplete) reference is : http://www.dvdcompare.net/comparisons/ which covers different releases in different regions, as well as special additions such as Criterion sets. It also covers, in many cases, the different extras available on different releases.
