Maybe to the original poster, why not convert the vid down to 1024 x768 for example?
If its hi-res to begin with you will gain nothing by playing it on a low res screen, there are video converters out there that will do the job and as long as you keep the aspect ratio the same they will look pretty good seen as its just anim stuff.
When you resize keep the horizontal length and choose keep aspect ratio, in your case 1024 leave rest.
You have to laugh at peeps trying to play hd content on netbooks, there is no point. The screen resolution is barely better than my old crt telly.
