BD Live? Where is it?
Blu-Ray is a lot of things, most are still in theory.
There are no blu-ray players that are capable of running an internet connection except the ps3. Even then, to run BD live it will need a firmware update.
The rest of the players on the market are simply stuck. They are known as profile 1.0, soon there will be 1.1 and then, finally, 2.0 which will have BD live.
Trust me, I'm an owner of a PS3 and HD. HD is currently more advanced.
