W7 does not natively read MP4 files, so they will not show up in the UI.
boardworks:I have a similar setup (large library on Windows Home Server of MP4/H.264) and cannot get the movies to show up in the "Movies" library. I have each movie (.mp4 file) in a folder with the movie name, and in each of those folders I have the .dvdid.xml file, and the movies do not show up. Now, if I add a VIDEO_TS subfolder, the movie will show up, but does not play when selected. Any ideas? /Videos /Movies /Back to the Future /Back to the Future.dvdid.xml /Back to the Future.mp4 /folder.jpg Thanks in advance!
