You can convert video to different formats ie DVD to mpeg,avi,mov using Xilisoft Video Converter Ultimate, even Nero has a reencode function. By the way I pm'd you regarding the video transfer hope it helps.
If its a round tube , go to any tire shop and buy a truck tire inner tube for about $20.00 , I have 2 round tubes and both have been replaced with inner tubes . If its a U-shaped tube sorry can't help you .
