DVD players do not play back CD with a 650nm (visible red) laser anymore. A few did at first, but even the cheapest models have dual lasers now. They use a second 780nm (IR) laser diode focused through the same lens, or sometimes a separate lens alltogether.Blu-Ray players will add a third laser; they will not be reading CDs with a 405nm laser, they'll use a 780nm laser.
And, must I remind you that SACDs *ARE DVDs*.
Sample rates are not changing. Frequencies are still operating off of the same fundamentals and multiples. The clocking shouldn't be any more of an issue than it is with current players.
If for some reason you believe that having a 405nm laser in the same chassis as a 780nm and 650nm laser will somehow cause degraded audio or video, I am *sure* that someone is willing to sell you a green pen which will clear that right up.
