I had been looking for a good media rack for our CDs.  I found a great one, the Max Steel 11 Tier Multimedia Storage Rack.  It does take a lot of assembly (luckily I didn't have to do it!), but it's awesome and holds so many DVDs!  But, now I need a second one!  I does have an anchor that you can use to prevent any tipping over, but we have not had to use it.  I would highly recommend using it if you place the rack in a carpeted area.  I am very happy with this item.
