ive never sent a game or dvd but i have bought some. i doubt you will find a padded bag that'll be able to post a game/dvd through the post offices slot thing. a dvd case is 15mm thick, a padded bag will add at least 5mm each side making a total of 25mm. unless you crush the case of course.only time ive recieved dvd's under that measurement is when posted in a plain envolope, that makes likely damage during delivery higher with the usual problems that brings the seller.
