[quote name='rabidmonkeys']IGN for awhile for games, but I've recently switched since I have so many dvds and cds, plus there is no where to catalog strategy guides. So I switched to a CueCat and MediaMan. Media man is free and uses the amazon DB for everything from CDs and DVDs to books and games, PC too. It also includes screenshots of most games and they have more rare variations then IGN does.
I used guzzlefish forever for CDS and DVDS but they suck ass so that lead me to MediaMan.
I grabbed a hacked CueCat on ebay for $12 including shipping, so I can just scan the barcodes on the back of the item and it goes straight in. Its great for folks who have larger collections. Plus you can export to CSV, TXT, or XLS. Then from there you can do anything.

For DVD's you should check out
DVD Spot. There's a lot you for with it, like keeping track of how much you paid for it, where you got it, when you watched it, rate them, write reviews, and there's even stats that let you know what actors appear the most in your DVD's and all that kind of stuff. It takes a little time to get your collection up since you need UPC's to find the specific DVD you have, but it's worth it to me. Mine is in my sig if you want to see how it looks.
