windows->netflix successfully?

[coolsnowmen]

Has anyone been able to watch something as video intensive as netflix on a virtualbox windows (XP/Vista/7beta I have them all).

My virtualbox vista had good sound at about 1fps, and my XP (despite having better cpu usage) all-but gave me the middlefinger when I tried to.

I'm wondering if I have something setup incorrectly (I didn't do anything special except install the guest additions), if I don't have the right hardware (I don't have a processor with virtualization extensions, but things like office run just find), or something else.

Version: virtualbox 2.1.2

EDIT: So my windows XP virtualbox can play movies pretty well (The audio was configured wrong), but vista (with video in "performance" mode) still cannot
