LG Internal Super Multi DVD CD Rewriter Burner

I installed one of these in my media pc about 5 weeks ago, and upgraded the firmware from YL01 to YL03 using the enclosed software and internet download from LG. It plays and burns Blu-Ray (up to 50 GB) and DVD (up to 8.5 GB) disks well, at about 1 GB per minute, using either the bundled Cyberlink software or other applications. So far I have not made any coasters with this device, but I have not been particularly aggressive about running other hoggish applications while burning. Five or so years from now everyone may be able to buy a Blu-Ray burner for $29.95, but at present this one is the best buy, and I'm happy with it. I don't own any HD DVD's, but it is supposed to play those too.
