Installing Pioneer BDR-205 Blu-ray burner as internal optical drive?

I'm not sure what 1.1 is? I have installed blu-ray drives in my early 2008 mac pro using ATA to sata adapter boards so they use the original harness and superdrive slots. Works like a charm and blu rays play fine in windows if you have an hdcp video card such as gtx 285.

Others do it by going to the spare sata ports on the mobo. Also, the Buffalo external usb blu ray drive works fine on my machine as well.

With Pioneer BR drives, be sure hard drives are not set to sleep in "Energy Saver" system preference.

I also have installed the Pioneer Blu Ray drive with a SATA to IDE adaptor and it works fine. My question is how to get the 5.1 sound out. I am trying to install an Asus D2X PCI-E card but need another power supply on the motherboard. My Radeon video card use up the 2 power supplies that I can see. Can I get an adaptor for an unused SATA hard drive for power to the card?

Are you saying that the radeon 4870 HD won't work if I wanna watch a blu-ray movie in windows 7?

The Radeon works fine in Windows 7. My issue is with getting 5.1 sound out.

I have a MacPro 3,1 with a NVIDIA GeForce 8800GT graphics card, and a Pioneer BDR-203 mounted internally via the internal SATA connector on the motherboard. Works beautifully for burning Blu-ray video, using Toast 10, and I use it to backup AVCHD files that are as large as 16GBytes each.

Would I be able to play Blu-ray video with Windows 7 on this system?

I had about given-up on Apple, and was ready to bite the bullet, and buy a Dell.
