Is there a way of playing quicktime files back to back without having to go to the computer and opening the new file and playing it after the previous file is finished?

Also, is there a way of making it full screen without getting pro? I opened my powerbook while in sleep yesterday and when I played a quicktime file at full screen, it went larger than usual (the play/menu bar was off the screen so that just the video portion was showing on the screen) but when I did it today, it went back to the standard full screen mode...

Try the VLC player from www.videolan.org
It's free and does full screen. I also think it has a "playlist" feature for back-to-back playing, but I'm not totally sure on that.
It also plays ASF, WMV, and other formats that Quicktime doesn't, so it's handy to keep around.

Cellulo is a nice video playlist app that uses the QuickTime engine and has full screen. Also the app I write might serve your purpose, though that's not it's primary function. There are many others, but VLC and Cellulo should cover most things, the others are mostly redundant
