Other than general cleaning and replacement of belts and possibly capacitors in the power supply. I can only make two comments.
ONE: There is a service that will convert VHS to DVD/Cloud/MP4 for you for what they claim is a reasonable fee (never used 'em)
Second: is why "It only works via RF".. There is an anti-copy code on the tape if you try to copy it without a code breaker the DVD recorder will refuse.
I don't do a lot of video work
But I used to do audio by the ton.. Same issue with digital transfers of audio. Analog did not have that issue.
