Got loads of cassettes and also VHS vids. I have a VHS to CD copier unit so that is easy.
I would urge you to get the VHS tapes done asap. I have been transferring around 200 tapes going back to 1979 but sadly many of the older ones are now unplayable due to mould.
Check each tape carefully before putting it in your player as any mould - usually in the form of a white powder - will transfer to the mechanism and infect your subsequent tapes.
