Or you can just look for:
Warlock 1989 720p HDTV DD5 1 x264 CRiSC
Which is something I've noticed... it is the same in regards to the recent release of SCANNERS on blu-ray in Germany as compared to the MGM-HD HDTV release. The German blu looks like a bad DVD upconvert, whereas the MGM-HD version is crystal clear (to the point that I never knew blood was shooting out of Cameron's veins during the final psychic fight at the end).
