Can anyone shed some light on the following questions for me?:
I have a Panasonic VCR and two Sony TVs. One of the Sony's is old
enough to have just the 300 ohm antenna input and the newer, cheaper
Sony has a choice of 300 and 75 ohm inputs. The forgoing was just
for differentiation. I can play back tapes in slow motion on the
older Sony just fine. The newer Sony shows a double image with the
same tapes played in slow motion. Both TVs work fine when the tape
is running at normal speed. By the way, before I worked out this
little triangle, I took the VCR back for servicing -- no problem
found. Are newer TVs cost reduced to the point where the sync
circuitry is marginal for VCRs? Do VCRs intentionally degrade the
output signal to assist copy guarding?
Second question, I like to record old movies, like Mary Pickford's
Sparrow, and occasionally the black and white VCR recording bursts
into what looks like multi-colored noise riding on top of the black
and white picture -- predominately red and blue alligned with
the scan. If I turn the TV color adjustment to black and white, the
recording looks just fine. However, if I look closely, I can see
short dashes which look like single scan dropouts. What is turning on
the color? So far I've only seen the problem when recording really
old films (silents) or Betty Boop cartoons. In fact, it can be
rather maddening. Last night I was recording "Man in a Cocked Hat"
which recorded beautifully up to the last reel and then the 'noise'
started. I know it was the last reel because the station botched
the transistion.
