Know anyone with a VHS /DVD recorder? that's the easiest way.
Did mine mostly by Viedo player + Scart to scart cable with a DVD recorder.
Others were done with Scart to RCA cable to my PC input
The only option, it would seem, would be to somehow capture the TV picture to laptop while playing the VCR through the TV
Does the TV have any output sockets?
tried videoing the TV screen while tape is playing?
