I was having the same problem. Make sure you select the file on the left, so it is gray. Then you should get more options in the drop down menu. The one you want is called file name.

My Sony bluray player reports 1:55:35 as the runtime.

Never mind. Seems that a bluray player software I had installed on the pc was causing the problem. It's solved. Now just figuring out the correct file.

I have another question regarding this this movie. I tried to rip the movie, but I am getting the following errors. It also failed to play in WinDVD Pro 2011, which no other bluray has had issues before. Error 'Scsi error - ILLEGAL REQUEST:COPY PROTECTION KEY EXCHANGE FAILURE - KEY NOT ESTABLISHED' ...

My Bluray Copy is 1:55:48, and the files that match those lengths on mine are 304.mpls, 450.mpls, 577.mpls, 868.mpls

So I guess it depends on which copy it is.

*304.mpls and 450.mpls didn't work for me
