I have got a copy of Proud Linus bolting at Doncaster unfortunately due to not being able to get the DVD copy to download I had to video it from my cam so the sound is bad and picture isnt the best quality but it serves the purpose.
Try putting the DVD in the disk drive, then loading it onto a program such as Windows Movie maker, then save onto your computer.
Im not sure you can do that with DVD’s though – may need to hook the computer up to the DVD player and play it through Windows.
Apart from that, can’t help sorry!
