I hate to be a pain......but here goes....I bought a CUDA enabled card to see how it could speed things up...It did, but the compression feature did not work...I decrypted 2 blu rays I have(37 GB and 33GB) to my hard drive and then ran those files thru DVDFAB and it's compression feature..It worked quickly but there was no compression...Any help out there??? It seems that the decrypted files were copied over again and DVD Fab said no compression was needed as I ran the saved files thru it..Am I doing something wrong??? Or should I re-insatll dvdfab since I installed a new graphics card??? Anyone???..Thanx..
