I doubt it. I had a client about 10 years ago that had betamax tapes they needed put into a video and it took us 1 week, 30 phone calls and 300 dollars to even get a betamax machine located.
I'll bet it isn't your tapes though, it is probably the heads on your machine. You could try a different machine (if you can find one) or get the heads cleaned (if you can find a repair shop to do it!)
Is there any professional service that can enhance old betamax recordings?
Many years ago I recorded on to used Betamax tapes. Some of the images are now degrading. Fuzzy lines across the screen and other, what appear to be, tracking problems.
