I forgot to add:

At WB, we could convert anything, recorded anywhere in real time (with 
hardware) or in software, after it was recorded.

>Have you given thought as to where you are going to get 50hz. power from? Here for line-lock 50hz. videotape machines, we have a 50hz. power source running at 220 volts. This is the only way to properly power certain machines that do not have a DC servo capstan and video drum (the capstan/drum is directly driven by the frequency of the AC mains).
