How to search for Movies/Tv Episodes with dual Audio (EN+DE)?

Hi, I was wondering whether anybody knows of a way to specifically search for stuff with dual Audio tracks (so you can choose in your video player which audio track you want to listen to).

In my case I am looking for english and german audio.
I usually download movies around 3-15 gig. I do not have the space do download full 40gig Bluray images.

Any specific release groups, terms/acronyms I could search for or different ideas?

Edit: Oh, I am d/l'ing via usenet.

BR & Thx in advance!

Narrow your searches to include DL or DUAL tags in the directory name.
