There are plenty of questions where people essentially want to know how to play their DVDs (How can I play encrypted DVD movies?, Lord of the Rings, Toy Story, another one).
Is there any way to know before you buy a DVD to know if it runs on your system?
Obviously, simply looking at the DVD does not help:
Is there any online service or another way to get to know if you can watch a DVD on your computer before buying it?
edit: Sometimes, Amazon customers give this information if it is not working. But I would also appreciate a "white list" of DVDs that do work.
As long as the region code on the DVD disk is compatible with your DVD player, it is fine. Instead of knowing a whitelist of DVD disks, it will be better if you know the compatibility of your DVD player/drive.

An alternative solution is to upgrade your player to bluray. All bluray discs are region-free, and you will not worry about incompatibility issues.
Install all of your DVD playback addons and you shouldn't have any difficulties playing DVDs. I've not run into any that won't play if you've got these things installed as long as you've set your DVD region code (necessary with a new DVD player). Easy to know, you won't be able to play ANY movie DVD if your region code isn't set...
Open a terminal and input these lines:
Install these (above) and you should be good to go. If you need to set your region code, go here (below).

You can go to launchpad.net and search for the name of the DVD, if others have reported that it doesn't work, you may find a report such as this one.
That's the closest that I know of for a 'black-list'.
