I reviewed this set previously. If you will scroll down a few paragraphs.
Although sellers/vendors of these 'gray market' DVR-R movies indicate the films are 're-mastered', etc., they are in fact just copies of the works of other sellers.
In the case of the Boston Blackie set, I was very very disappointed. Quality is poor to horrendous. This particular set will not play on my DVD player but works on my computer. I got the message 'Improperly Formatted' when trying to view these films on a conventional DVD player.
I only watched a few of the movies. They are grainy, dark and have the logo of various TV stations in the lower right side of the frame.
Definitely not worth the money I paid for this set.
I do NOT recommend purchasing this set from ANY vendor unless you are absolutely desperate to see these movies and tv shows.
