Thanks for the reply, The equipment I have in mind for multiplexed tapes is intellimux which isnt that expensive, i have been using it for a while and not had a problem if you know the make of the orighinal multiplexer. I already have a lot of software for DVR, The thing i found with DVR's is that everything players on different players however again its not too bad if you know the system that it came from. As for extracting data from the DVR's, i pretty much think im an expert in that field and certainly a leader in scotland, as i said if bieng doing it for a while now, just not for defence of insurance companies????
