During emerging dvdrip today, the packages "dgs" and "arts" where not recognized as part of the depencies and had to be emerged manually. (just a small bug, but a newbie might fail on finding out where the missing libraries are contained in) :)
It worked without arts and dgs on my box. Can you point me to the error? -phoen][x-
Cannot say that I had either as well, and I used it a few times already.
