OK, the files are just photo's put through a program called Pro Show Gold.
On our travels I used to do a lot of photography and then put these photo,s through the program added transitions and music and presto a DVD was created which I could play on the TV or Computer
So that is about it really nothing to complicated but now I have heaps of these DVDs which is fine but I just wanted to reduced space and put them on a USB and play them when ever.
Thank You
