First of all, we have watched 6 episodes and they have been great!!! Awesome Avengers show!!!! I live in the U.S. and these Blu-Ray discs play just fine. I thought that would be good information to give out, because the U.S.VERSIONS of the Avengers show were only released in 6 to 7 episode dvd's so far. This dvd set was released in Canada and it is the complete 26 episode first season.
