Premium video content subscriptions

[emailapphost]

I want to add premium video content for paid subscriptions.
Are the any good examples of sites who have done this.

I try to upload my video and get this error message:

SANY0032.MP4:
Invalid File

Is this because .MP4 files are not supported?

Did you add .mp4 to the attachment manager?

I did it now - and it works.

Thank you.
