help! DVD Player is driving me crazy!

I like to multitask on my macbook pro. version. 10.5.8. And ever since the last upgrades of DVD Player, (newest version i have is 5.0.3) I haven't been able to work on any other application as DVD Player is playing my DVD. every time I click off of the player it pauses. I've tried playing with the preference settings but can't seem to figure it out. What is going on?? I use to be able to play a video and work on safari and illustrator at the same time! Can i play it on Quicktime? cause I've tried opening that up, but not sure how that works. never used it before. This is driving me nuts! gah!

Note: moved to appropriate forum.
This is not a site comment or suggestion.

First thing to try is run Repair Permissions from Disk Utility.
Next try dumping the DVD Player preference file.
It is located in Users / your user / Library / Preferences / com.apple.dvdplayer.plist
Close DVD Player - Move that file to the desktop - Re-open DVD Player

Let us know if one of those works or not.

thank you! it worked! Your a saint!
