I'm a noob when it comes to this - I started ripping my DVD's so I can convert them to watch on my Pocket PC, which works very well except that the first one I did some time ago I didn't save all to one file as DVD Decrypter does have an option for that but I didn't find it until after I had done this one.
Do I have to do it over or can I somehow combine the 6 or 7 files into one using some other software?
Of course, this is using DVD's that I personally own and for my own personal use (Fair Use).
Thanks.
