I've just recently started watching Blu-Ray movies on my computer. I'm using WinDVD 2010. So far I have seem 3 movies which were all fine. Terminator 2, Death Proof and Planet Terror. The 4th movie "The Day the Earth Stood Still" (2008 remake) Has audio problems. Specifically the voices all sound far away and muffled. Background audio like music and special effects all sound great. If I change the audio to French for example, the French voices sound great. But I don't speak French so that doesn't really help me. Also, the Directors commentary track sounds good too. Any help is great. I've gone all over Corels's forums, this forum, upgraded my sound drivers, checked every setting I could find. Nothing works.

Assuming you have the original release of T2 rather than Skynet Edition, "The Day The Earth Stood Still" would be the only title you listed that uses DTS-HD MA. I would start troubleshooting there. Can't provide any more assistance I'm afraid as I'm not familiar with WinDVD. Perhaps try the HTPC forum if you haven't already.
