I have bought a few films from the Itunes store recently and have been quiet impressed to date. However before I get to carried away I need to address a few things as I am sure there is room for improvement. How good is the quality of the films I am downloading & what,s the name of the format? & can I convert them to get better quality and still be able to watch them on my Itouch and Mac etc. I don,t know much about film quality etc so would like to know the basics so I can get it right in the early stages. Many Thanks
