There are a lot of you guys out there that know a lot more than I ever will. My question is, if you leave the setting at the default and you backup your movie and all seems to go well, you think you have a good backup. But when you play it you have freezing, distorted and such. This did this on The Bourne Ultimatum. I think I read in this fourm that it had no protection. So how do you know what setting to use, as all goes well till you watch it. Do you keep makeing coasters till you get it. So how do you guys do it.
