I've downloaded an MP4 of a Youtube purchase and cannot get it to play in Windows Media Player, Quicktime or Real Player. It was downloaded with FlashGot, the program I installed in Firefox, and has appeared as four MP4 files, one of which begins with "▶_" in the file name.
I think I need to decode it somehow, but have never done so and am not sure how to begin (if that's the problem). Any help would be greatly appreciated. Thanks

Try changing the name to something simple getting rid of "▶_" which might be causing problems?

Netmask56: thanks but my download resulted in four files, only one of which has the ▶. None of them play.
Davexnet: thanks again. I looked at the details via mediainfo and came up with the following for each of the four files:

Encryption : Encrypted -
Davexnet: thanks. Is there any way to decrypt them?
Atticus Draco: thanks, but I had trouble doing anything with these files using VLC (perhaps the encryption circumvents any operation, even conversion?). If I should be able to do what you say, could you provide some guidance on how to convert with VLC? Or perhaps link to instructions that explain how? I had a hard time finding any myself. -

I had a hard time finding any myself.
menu item: "Media" (select)
--> 'Convert / Save' (select)
another box will open,, go at it,, it's pretty self explanatory after that
it shouldnt take long,, 'coz it's already a .mp4 file,,
what you'll be really doing is changing the header of the file to an acceptable codec heading
(as far as i can guess)
what i dont get is this:
