MP4 Copy Protection

Can MP4s be copy protected? I'm not talking about Apple's MV4 file type. Or are they like MP3s where copy protection is not possible?

If an MP4 is copy protected how can you tell, if you're a valid user?

Maybe it relates to FairPlay?

Yeah, I found the FairPlay, but this didn't come from Apple and to be honest I don't know if it is copy protected. I was wondering if first of all an MP4 can be copy protected, and if it is how do you know.

Are you talking about mp4 files (a video container: »en.wikipedia.org/wiki/MPEG-4_Part_14) or m4p files (Apple's copy protected container for AAC audio files)?

As far as I know mp4 files are not copy protected??

I'm talking about MP4 files, ie VIDEO.MP4. I have a subscription to a video service that allows you to download the videos as MP4 files to use on your mobile devices. My question is, what happens to the MP4 files I've downloaded if I decide to cancel my supscription? There may be some information on the site, but I was wondering, in general, if MP4 files can have DRM.

Test on a PC that has not been used to play the movies and is not connected to the internet.

If they are protected, they won't play. Some protected files won't even play on a PC not connected to the internet, whether the PC was previously used or not.

I put them on my iPad and played them, but it was probably connected via wireless. But, I wasn't prompted for credentials to play them. Don't know if that qualifies or not.
