if you have 'easy debian' for the n900 installed then you can install it from the debian synaptic app installer, along with the 25,000 other linux apps. as the poster above points out, speed isn't great, but it's very usable for short clips like music videos or clips taken from the n900 camera. check out the 'easy debian beta testing' thread for more info if youre not familiar with it. if you are familiar with it, then just use the synaptic installer.
