Mark, you are doing a really great service by posting those videos,as im sure that they will be in the future, and most probably have already been in the past a great help to people.
Therefore, any that you can put on in the future will be of great help to manyi am sure,i have been helped in the past by at least two sets of repairs to b and o items on beoworld which have been photographed in stages,one being the replacement of the loading tray belt on the cd 50.
So showing any repairs in video form can only be a big bonus!
Besides it beats watching a lot of the rubbish they put on television these days
