AutoPlay QuickTime Movies on Open and Useful QuickTime X Hacks

QuickTime X

QuickTime X is really cool and one of the many great improvements in Snow Leopard, but As most people are probably aware, the new QuickTime X Player in Snow Leopard has no preferences and that QuickTime X no longer automatically plays movie files on open. Thankfully resolving this is just a matter of entering a command in the Terminal. Well we had show some more QuickTime X hacks, like forcing QuickTime to stay full-screen even when it’s in the background, or how to force the titlebar to always show or always hide.

Each one of these commands can be reversed by changing the value from 1 to 0 or vice versa
