Improving quality of AVI movies?

I have Anchorman on my computer and i want to burn it on a DVD but i want to know if there is a way i can improve the quality before i do?
its not that bad quality its very watchable, but it is a little blurry and i was wondering if there is any software i can use to sharpen it up a bit?

There's no way that i know of where you can improve the quality-look. Only decrease. You might have to just live with what you've got.

It will probably look less blurry on a TV anyways, because TV's operate at a much lower resolution.

thats true, ill just burn it anyways

you'll have to just redownload it or watch it on a smaller screen.
