Whenever I need to convert something, I'll use either Handbrake
. Both are free. SUPER has a ton of options but Handbrake is nice and easy to use. With Handbrake, just make sure you select a preset that suits your needs. SUPER is a bit more involved, and a bit of a pain to download from the link I provided. You have to scroll down to the end of the first page and hit the "start downloading SUPER" link, then on the next page hit "download and use" then finally scroll down to the end of THAT page and hit the "download SUPER setup file". Personally, I'd recommend you check out Handbrake first.
