*Sigh* Running Vista 64 ultimate. I really need to view thumbnails of m2t files. Here's what I've done so far: Added the following to my registry Windows Registry Editor Version 5.00 [HKEY_CLASSES_ROOT\.mts\ShellEx\{BB2E617C-0920-11D1-9A0B-00C04FC2D6C1}] @="{c5a40261-cd64-4ccf-84cb-c394da41d590}" [HKEY_CLASSES_ROOT\.m2t\ShellEx\{BB2E617C-0920-11D1-9A0B-00C04FC2D6C1}] @="{c5a40261-cd64-4ccf-84cb-c394da41d590}" [HKEY_CLASSES_ROOT\.m2ts\ShellEx\{BB2E617C-0920-11D1-9A0B-00C04FC2D6C1}] @="{c5a40261-cd64-4ccf-84cb-c394da41d590}" I associated .M2T with WMP. I now get a thumbnail of the WMP logo with any m2t file, but no thumbnail of the actual video like I was hoping (Like with a .mpg or .avi file). Also, if I double-click an m2t file WMP tells me it has no idea what an m2t file is but it will try to play it, which it does. HELP
