How do I remove white streaks?

No loop...my setup is VCR out (RCA) > ADVC IN

Your VCR does not have a SCART by any chance?
If so, I'd recommend wiring pins 13, 15, 17 and 19 of the scart to pins 2, 4, 1 ,3 of a Y/C connector. Like so: http://pinouts.ru/VideoCables/scart_svhs_pinout.shtml

This is highly recommended over just RCA (composite only) > ADVC300.
I, for one, have seen huge improvements just doing that.

Thanks...yes...I do have a SCART connector. I will have to try that.
