It would be both club CD's for testing and o/p from Gary's applications.
But please don't spend time on this.
I will need to recreate that missing frame pulse, but your circuit looks to be too complex for me. As your circuit was mentioned on the NIPTRIX post I thought I would have a look at it.
I also have Peter Smith's frame pulse inserter circuit in recent newsletter and also a one chip missing pulse inserter by Jeremy some time ago. ( newsletter 21/1) Neither as accurate as yours, no doubt.
Steve , I do hope that you will not be offended in my remarks. Many guys here seem to understand all about PIC and all the rest, but I can never get my head around much above ohms law.
added.....I always use the very old club sync seperator circuit which doesn't have the clamp line. So additionally if I built yours it would mean my going a new way and I have enough trouble at present with the NIPTRIX
