I sometimes want to put movies on a dvd that I recorded on my Tive series 4. The only way I know how to do this, is to play the movie from the Tivo, and set the dvd recorder manually to record. This gives me a dvd that plays in my dvd recorder/player, but If I want to make a copy for a friend, it won't work. The copier I have won't recognise the disc. Same problem with my computer. Tivo tech support thinks it's because the movie gets saved as a .tivo file. Is there a way to make the disc universally readable?
