I came across an article in the August 2002 issue of VideoSystems magazine which discusses "frame mode"s various incarnations in great detail. You may find this an interesting reference.

I'm going to bump this up.

Good idea, Frank. I forgot about this. It's a good article.

Thanks for posting the link; notice it's written by our own Steve Mullen, one of our forum moderators. As I've said before, we're all very fortunate to have Steve join us here with his wonderful expertise and knowledge base.

the aricle was about NTSC equipment right? Does the section about frame mode refer to PAL equipment as well?
