I managed to do some testing on the MK2 yesterday and today and i was still getting a speed problem which now comes down to just fiction of the recording process embossing the recording on the record .
So the problem i have been having is the recording is slowing down the platter a touch so the video plays back faster .
For now have over come this problem by eddy current braking using a hard drive neodymium magnet
So at least i can display something ..todays test recording is this youtube video
