Congrats. Here's a couple of websites you may find useful:

http://www.dvdrhelp.com/dvdhacks.php - search for your player here to see if and how those "features" like macrovision, forced commercials and region-locking can be disabled.

http://www.dvdpricesearch.com/ - look up any DVDs you want to purchase here first to make sure you aren't overpaying.

http://www.dvdtalk.com/ - all kinds of information about DVDs, past, present and future, my favorite section is the 'DVD Bargains" forum which has helped me to find some incredible deals on DVDs (like an 8-disc collection of french movies with an MSRP of over $100 for about $15 at BestBuy)

http://www.avsforum.com/ - don't read this forum much, else you'll end up going broke as you upgrade your system.
