Get the print from MPI
You might want to wait to see if an authorized DVD print of the film comes out in June 05 as anticipated, but if that doesn't materialize, let me recommend the VHS version from MPI Home Video. It's fantastic.
It's the only print in any format restored from the original negative -- as close to broadcast perfection as you're going to get. Producer, co-star, and #1 son Michael Wayne supervised the process, so you know it was done to his satisfaction.
I bought McLintock on DVD from Goodtimes and again from some other studio, and ended up tossing them both out in disgust. Yeah, there ought to be a law, but don't make the same mistake.
