Hello.  I'm rendering an mpeg2 segment using mpeg2/custom/system/and checking the "save as separate elementary streams" button so that my mastering people can import my files into DVD Studio Pro.  When I open the mpa file in Windows Media Player to test it, it plays fine and has a length of about 1hour and 10 minutes which is correct.  When I load the m2v file into Windows Media Player or Real player to test it, it says the length is 52 minutes!  I have no way of opening the m2v and mpa files at the same time to see what is going on.  I can't open the m2v file in Vegas because it's not supported.  
I just want to make sure I don't drive all the way to the mastering place with my hard drive only to find that the video track has some how become shorter than the audio track!  Thoughts?
