I know this was asked before, but I can't seem to find the thread. Sorry. How do you combine movies that come on two disks into one mp4 file? I am trying to encode the extended version of LOTR. Before I had an ATV I simply used QT Pro to combine the two files. But this produces a .mov container, which plays fine on the computer but not on the ATV. So, is it possible? And if so, how do I do it? Thanks.
