Hello Greg,
I've got for you two links on the E-bay to Blue-Ray drives. The
Panasonic Blue-Ray Burner Internal Desktop drive and
PIONEER-BD-DVD-BLUE-RAY drive. This last one is a little too expensive, I suppose. These two drives you can swap into your desktop instead of your current drive or just add to the present one if you have the free bay.
You can always get the
external USB-DVD-RW burner drive and use it on both your computers.
In addition to the Blue Ray drive you will have to get the
Cyberlink PowerDVD9 software to play the Blue Ray discs. There are other applications as well, prehaps even free ones, but the power DVD8 or Power DVD9 are the ones of the best.
Btw, this Sony Bravia is the TV set, right?
Hope I could help you somehow. Cheers...
