Is it possible to hash flv videos so it is unplayable by itself and the format is unrecognizable by softwares, but i could actually de-hash them and play in my as3 script?

This is going to be realized on a CD so I can't use server scripts.

+1  A: 

no, you can't. not with flv. you could however embed the video into an swf and encrypt the SWF. please note however, using a strong encryption for video data may lead to performance problems.

anyhow: you can load the binary data into a ByteArray, perform the decryption and then load the SWF from the ByteArray.
