Removing Dot Crawl?

[Penthode]

The DVD player of course has a Y output. That is the solution for that. Thanks.

But the solution for the DTV OTA box is way too cool! I suppose the key is finding the NTSC encoder. How did you locate the encoder?

I have a Zenith box and was thinking of simply Googling the devices on the board to find the NTSC encoder. I like the great idea of being able to switch the color on and off.

Thanks, Terry
