I am using Compressor 4.0.4 on an iMac, OS X Mountain Lion, i7.
Every time I go to compress a 90 minute .mov file in Compressor (haven't tried other file types) on my home computer it goes all the way until it shows having about a minute left and then Compressor just stalls. It never gets to the point where it asks me to insert a blank DVD (i.e., it has already created the .m2v file and the .ac3 file(. I know the burner is okay because I can use Toast 11 to burn DVDs without problem.
I have virtually the same computer at work and Compressor 4.0.4 works fine. At home I tried reinstalling Compressor to no avail, tried trashing preferences, repairing disc permissions, zapping PRAM and even then followed an Apple support page where it said to trash the Apple Qmaster folder in Library/Application support, which i also did, still to no avail.
Please help...
