I've got some mp4 movies that came with a .thm file and when I put the file onto my memory stick and go to the movies in xmb the thumbnail pictures won't show up, all I get are those grey default boxes and the movie title etc... I can play all the movies, its just missing a nice thumbnail picture which would help me organize things. I've tried creating my own 160x120 jpg of the movie cover and renamed it to M4xxxxx.THM (movie name) but even then there is no picture showing up, just the damn grey box. I'm running firmware 3.10 oe-a2 and the mpeg-4 movies and thumbnails are in the Video Folder.
Thanks in advance for the help
