My pleasure. Curiously enough, I wrote that post several years ago and recently had a similar experience in that I was getting a lot of pixelating, freezes, bad behavior so I changed my cable box and had the same problem again. I searched the internet and came onto this post and tried it. It wasn't until I was done that I realized the fellow who wrote it was me. I had forgotten. Anyway, thank goodness my tinkering worked, as I understand it, for a number of people.
