  I am looking for a converter box for a frame grabber I am building. I need
to convert cable TV video (most likely channel 3) to composite video
(NTSC baseband). Does anyone know of such a converter? If so, who makes it
and how much does it cost?

  Let me offer a few more words of explanation for this. The VCR I own does
have a composite video output but the sync pulses are not very good. I have
been working on a stable sync separator circuit for months without luck. After
examining the composite video signal inside my TV, I learned that the sync
pulses from the VCR were pretty bad. I would prefer not having the VCR
generate a channel 3 signal and then drop it back to baseband, but the TV
picture from the VCR is fine so I'm sure this will work.


     Thanks in advance for any help,
