thats actually not true. There are some 5.1 profile x264 videos that the ps3 just cannot play. The ones that it can play that are labelled as 5.1 are usually mislabeled as 5.1 and actually are 4.1. Changing them from 5.1 to 4.1 atleast makes the ps3 attempt to play them. So to the OP, unfortunately the only chance you have of watching this movie on your ps3 is if you convert it to a format that the ps3 does play, or if you have a strong enough computer, you may be able to do the decoding on your computer and have it streamed to your ps3.
