I love this thread. I continually read that Blu-ray and HD DVD, unlike DVD-A are not limited to 96kHz/24-Bit 5.1 and are capable of 192kHz/24-Bit 5.1 lossless audio. I can't find any proof of that anywhere including the official DTS site for DTS-HD MA, the Dolby Digital site and any of the Blu-ray player sites. The White Papers for the various formats I could find offer no proof and there isn't any software I can find that goes above 96kHz/24-Bit for 5.1.
Can somebody point me to a definitive statement on the issue? At 55, I don't think I could hear the difference in any event, but for academic purposes, I would like to read about it if true.
