I've been a very long time Netflix user, especially streaming since I rarely get the luxury of watching movies on TV. Hollywood and other players make it a little difficult to watch netflix on Linux machines. Apparently they're more scared of the small minority who want to abuse the system rather than genuine end users.
So I run Windows XP within a VirtualBox VM ( those factory installs of Windows come in handy despite the fact you're forced to buy them). But running Windows XP was causing all kinds of audio twitching and the video would stop playing after a minute. Quite annoying.
Turns out all I had to do was to dedicate 1 CPU to it instead of the 2 that I had. Everything's been working fine after that.
