PhotoBucket help.

PhotoBucket help. How do I transfer my videos I put on PhotoBucket back to my pc. PhotoBucket has changed the format from mov. to flv. for some reason when you tried to transfer it back to your pc it wants to go on your pc as html. file so how can I get it back to mov. and get it off PhotoBucket if I try to click and drag to my desktop it creates a internet shortcut to the PhotoBucket page. Also how do I transfer my photos back if I ever want to. The reason I put them on there was to clear up space on my pc and so I could back them up when I done harddrive restore format to original factory settings. Any help would be great thankyou.
