I don't really have any problem with most DRM methods but when they become obtrusive I get really irritated...I was in the middle of playing Half-Life 2 when I was promptly disconnected because someone had to take a phone call (it's a old 2.4 ghtz phone that disrupts wireless internet) as soon as I was disconnected I was booted from the game. DRM like that is definitely unnecessary, and seem to promote piracy more then it stops it.
