The packaging claims this movie has 5.1 Dolby Digital Surround. My player and DVD Shrink say it's only a stereo track. I know the DVD cover could be wrong but is there any way to test it or find an answer? I especially double dipped from my Anchor Bay release because I thought this one had an upgraded audio track. Note that the volume label for both discs is the same and it's a direct Anchor Bay transfer because a music cue is missing in the same spot on each. Could DVD Shrink just be pulling up the info from the AB release but it actually has a 5.1 track?
