Hello. I am running a non-mirrored dual-display setup on my 15" Macbook Pro (snow leopard) for the 1st time, and am trying to figure out how to do the following. Currently, I just can't get it to work. I'd like to run my normal apps, such as Firefox, etc. on my built-in display with the menu bar and dock. I'd also like, at the same time, to be able to run full-screen iTunes, VLC or DVD player on the HDTV, and be able to switch to my built-in display without disrupting the viewing on the full-screen video on the HDTV via iTunes, VLC, etc. Any ideas on how to do this? Thanks.
