Is Hi Def 48k or 96K, or are there different standards for broadcast vrs printed (DVD-V, DVD-A, SACD, etc.)? The reason I'm asking is because I just read the latest issue of Surround Professional and there was an article the Grammy Show and the different mixing engineers. One was using a DM2K, another was using a pair of them, and the last was using a Sony Oxford (He was doing the Mono, Stereo and Pro Logic 2 Mixes).
Since the Sony won't go past 48K, it made me wonder what the official breakdown is on this stuff.
