First, this is NOT a minus. If you live in the USA can't watch these DVDs on your TV, it's because you don't have the right DVD player. I live in the good ol' USA and watch DVDs that come from all parts of the world. That's because, years ago, I bought a region-free DVD player that will convert PAL to NTSC on the fly - allowing me to watch PAL DVDs on my US television set. If you can't do the same thing, there are two ways to "fix" your problem:1) Go to the VideoHelp.com forum (it's free). Mention the make and model number of your DVD player. Some (but not all) DVD players can be turned into region-free players simply by entering a short sequence of codes using your player's remote control device. Once those codes are entered, your player's ROM settings are changed permanently - allowing you to watch DVDs from anywhere in the world *forever*. And it won't even cost you a dime. Or ...2) If you are unlucky and don't have a player that can be modified with codes, type "region-free DVD player" into the search block right here at Amazon. They have a bunch - most under $50 - and some that can upconvert the signal to 1080p quality.Now, on the Cosmos set itself. I edited this review from when I first posted it ... not knowing exactly how they arranged programs on the discs. I originally thought I'd found a number of flaws but now realize I only found one. At the end of episode 3, the credits are cut off prematurely. That's it. Otherwise, the set performs well and I'm very pleased with it.
