Lysanne hi,

"stuttering" movies can be a pain in the neck :)

Slow streaming results in "movie stops and start" problems.

There's a small free solution for this - download SpeedBit Video Accelerator.

(Disclaimer: I work at SpeedBit :) )

This small piece of software does EXACTLY what you want, speed up your youtube videos, while staying quiet as a mouse the rest of the time.

It doesn't take up a lot of memory, and it has a built in "video search" feature which is very nice.

Currently, it supports youtube only, but future versions will support more video sites.

Enjoy!
