BLURAY REQUIRED CHIPSET

What? As long as you have a BD drive you can watch Blu-ray. Just make sure that the software supports BD. The chipset has no relevence except when it comes to playing BD with on-board video.

Tried PowerDVD Ultra, WinDVD and CinePlayer.
WinDVD will do the video, but not the audio.
I purchased a stand alone bluray player after
trying unsuccessfully to play bluray on my pc.
I am however going to give it one last try.
I am building a new pc with the following:

MB GIGABYTE GA-MA790FXT-UD5P AM3 R
AMD Phenom II 965 Black 3.40GHz
2 each Kingston 8GB (2 x 4GB) SDRAM DDR3 1333 (PC3 10600)
Sound Card - ASUS XONAR DX 7.1 PCI-e
Video Card - GIGABYTE ATI Radeon HD5750 1GB DDR5 PCI-Express
Pioneer Model BDR-205BKS Blu-ray Burner
Windows 7 Ultimate

Cooler Master COSMOS 1000 RC-1000-KSN1-GP Full Tower Case
Thermaltake PSU TRX-1200M TR2 RX 1200W W Active PCI-E ATX 12V Retail
6 each Western Digital WECB1TB 1TB Caviar Black 3.5" Internal SATA HD's
Logitech Z-5500 - 5.1 505 watts Speaker System with THX & Dolby Digital

No more creative sound cards - too many driver and software problems.
No more PowerDVD either - overkill plus too many software updates just
to get it to work.
I will probably use WinDVD - at least it previously got video.

If this doesn't play bluray, I quit.

If your monitor does not support 1080 resolution it won't matter what system you build. Your monitor will need to be at least 1920 x 1080.

Thanks, but monitor is 1080 and HD from other sources work just fine.

Download VLC. Then try opening .mt2s in the stream folder. Also try QuickTime (Note: I'm not a fan of QuickTime, but it seems like it can play BD). http://www.apple.com/quicktime/player/

I seriously think this is a BD drive or software issue. It is VERY unlikely a chipset issue.

Thanks for responding. I tried your suggestions to no avail. I am going to take a break on this particular problem. If and when I ever find a solution I will let you know. It is more than likely an error on my part. I just haven't been able to figure it out yet. I am not a quitter and will eventually get bluray to play on my pc.
Thanks to all that responded.
