Problem Type:
Function does not work
Problem Description: Since testing 1.08 no mp4 files show up when browsing files on my 360.  It worked with 1.06.  Now of course I understand I am running a beta but wanted to bring it to your attention.  
The only file types that show are AVI and WMV 
Test Procedure (steps to reproduce): Install 1.08 and then browse you video library on the 360
