If your tapes are overly dirty the interferance can be seen by the VCR as copyright protection. It's not Cyberlink.
It's possible the VCR is a dirty stinker also. There are instructions on the internet for cleaning heads. Pure alcohol, NO COTTON Qtips, no paper strips, spin the drums by hand, read up. Maybe try a different machine.
The only way to guarantee you can capture your tapes is to incorporate a WORKING time base corrector which will scrub the noise from the tape. You will have to pay through the nose, I paid $400 for mine 2 years ago and they are upwards of $6-800 now because nobody makes them anymore.
Go to DigitalFAQ.com and do more research.
As for a USB dongle, make it a VC-500 or don't bother.
