Well I don't know anybody who has every single episode of MITM on DVD here.
But I know some other options.
You can watch seasons 3 and 5 on Youtube.
Go to this guy's channel http://www.youtube.com/user/JetGrindRadioz
Hurry up and watch 'em because eventually he will get banned
I think they have seasons 1,2, and 7 here to watch.
The site is in Chinese but just click on the videos.
