Universal still hasn't released Seasons 5 & 6 in North America, which is why I ordered this set from a British company. It doesn't say on the ad, but this DVD will only play in Europe, Australia, and South America. I have a region-free DVD/Blue-Ray player, so it's not a big issue with me, unless I want to lend out the discs.
As for the DVD set itself, it's pretty basic: you get all 22 episodes and that's it. No subtitles, no liner notes, and of course no bonus material. There are some previews at the beginning, which you can skip over to get to the menu.
The quality is good. Sound and picture are fine with no flaws.
It's about half the price of the Anchor Bay version, so if you live outside Regions 2/4, and you can't wait for Universal to release Season 5 in your part of the world, and you have a way to play these, then yes, it's a good deal. And if you live in Europe, then go for it. It has the other episode where Xena sings.
