so i just got a hand me down dvd burner, and have been trying to convert some media to vobs and burn it so i could watch it on my dvd player. I get the vobs, they play fine on the computer but once i burn them the dvd pixelate and eventually lock. They start out fine, but in three or four attempts they always end up doing the same thing. Same thing when i try backing up a dvd. Any help is good help...
