Did you have video's of the horse dancing on your computer or just links to a Youtube site with horse dancing.

If the latter just go to YouTube and in the search box type horse dancing.

If the former get somebody to download Ubuntu Linux and burn the ISO to a cd.  Boot from the cd and mount you computers hard drive.  Search for the files and then save them to a cd or external hard drive.  Ubuntu has the ability to do either quite easily.
