I seems to be having problems recording movies vcr-vcr. What happens
is that the recording vcr receives some signal from the replaying
vcr that either removes the blanking pulse, distorts it, or
messes up the sync pulse. I may be wrong entirely but atleast I'm
sure that the signal is tampered with to prevent recording. I don't
know why anyone would want to do that since it's for only home use,
but I want to get around it. The symptoms are if you are viewing
from the recording vcr end, a slight but periodic change in the
brightness of the screen. This is not the case if you just want
to view the movie.

Any of you guys got any circuits out there? Really appreciate it.
