Salt DVD ripping issues

[greatlakesglen]

I have a double feature set that includes Salt and The Tourist on two discs. It is North American (Canada) and is from Sony Pictures Home Entertainment. My trouble comes when I try and scan the disc for Salt and all I can see with MMKV are the extras on the disc. There is no main movie file showing. The disc will however play the main file under VLC as well as Media Center, so the file is on the disc. I've tried MMKV on my testbed system as well and the same results. This is the first disc that I have ever had that will not show files correctly. Not sure what to do at this point. Any thoughts?? Thanks.
