Hi Jeffrey
Thanks for your files.
I will keep them safe until I start at this again. I am distracted at the moment too.
Getting good clean reliable sync from a VCR is a real problem.
Lately I did try and use a LM1881 to extract the odd/even field from the VCR signal. But it didn't fare any better than doing it digitally. Both failed to the same extent.
I have to say though that the test I did with the LM1881 was a very brief one and I didn't try changing the values of the R's and C's in the circuit so there may be potential for some improvement.
