This is prolly posted elsewhere but I just got back from a friend's home....I have the trial of DVD Fab and had a copy of a tv show that I have and took it over to his house to watch...it works fine in my machine at home but it is a new machine. It won't read in either of his players-they are 3-4 yrs. old....any advice? I have both +R and -R DVDs and neither worked. Thanks in advance. The plus Rs are Dynex, the minus are Memorex
