I agree with you completely and I probably misunderstood the question focusing on the Title - changing vro to mpeg - again, not a bright bulb in this string of lights.

I don't understand why a file extension or type would have to be changed to simply copy from one storage device to another but I am also in the dark re DVRs having never had a use to acquire one.

I have also seen people encounted the data error (cyclic redundancy check) when doing a number of operations - one of which is trying to mess with encrypted files without going through the step to decrypt them.

Thanks for helping me see the core issue more clearly.
