definitely yes! with 16RPIs in cloud.

what is basic data rate of dvd speed 1x with mpeg2? 10mbit/s?

ok, that's 1.2MB/s, writing. but you need read as well. so your RPi will barely read encrypted data, maybe with the same speed write them to output.

and we missed decoding. and we of course want the audio as well. but we spent all the cpu cycles on reading the drive

Hahaha

Write the ISO at 1x and it will of course be read a 1x (realtime) giving us just 2.4MB/s of io.

Decryption at this slow speed shouldn't be too heavy on the CPU but this is speculation as I don't have the hardware to try it, the GPU will be playing the ISO. Seems theoretically possible and in the end you would have an unencrypted ISO of the DVD.

I'm sure no Xbian developer is going to take this on, just throwing ideas out there for someone who might want to give it a go.
