Acturally i prefer DVD at home, it's more conveinet and cheaper. but the thing is DVDs are easy broken which can not be played anymore, i've been broke several of them. so later i convert them to my pc and ipad,ipone, so i can exercise anywhere at any time. drm-assistant.com/dvdrippingsoftware.html
