Leon: International Version
We've been getting a steady stream of reports that the Region 1 release of Leon: International Version has a problem with its Dolby Digital soundtrack. Many people have reported that the rear channels are very quiet in comparison to the front sound stage and that the pro-logic version on the same disc is far more involving.
While I can't check this myself as I don't have access to a copy of the disc, it does appear that there is almost certainly a problem. There is currently no word from Columbia as to whether the disc is to be remastered although I personally feel this is unlikely to happen.
I am going to try and locate a copy of the disc to compare to my Japanese Region 2 release - as far as I know, the Japanese disc is unaffected by this problem.
