Can anyone recommend some decent DVD copying software.I have a DVD, which is itself a copy, that I want to copy onto another DVD.The disc is only a load of martial arts exercises, but when I copy it using Nero, the files copy to the new disc ok, but when I play it on my PC the video is speeded up and everything looks at though it is about 5 x the speed of the original disc.I have also tried DVD Shrink, and have even tried converting the files using WinAVI, but the results are always the same.There are over 300 files on the original disc and also many menus.I simply want to copy the disc, with its menus, onto a new disc, but I dont know why it is going wrong.Any help would be most appreciated.
