I would like to know if anybody has purchased the new 4k version of "Butch Cassidy and the Sundance Kid" that Fox recently made available. I would like to know the quality of the video and audio. I have read the current Blu-ray video and sound quality is not very good. The movie was released in 1969 so I would like to know if they were able to really improve it a lot over the Blu-ray version.
