When trying to start the encoding process TMPGEnc brings this message up... "To playback MPEG-2 file, DVD software needs to be installed on your system. MPEG-2 files cannot be played withouth this software." I have a DVD-Rom shouldn't that be enough? And everytime I try to bypass the message and continue trying to encode, TMPGEnc freezes up and doesn't respond. Any suggestions? Thanks.
