Am I missing the point? My understanding from my A level electronics (few years ago) was that an analogue signal can be distorted, but a digital signal should not be subject to the same problems. My recall is that the bits were either there or not, and if they are not, then the device (not HC but other instruments) should, with various checks be able to detect any significant loss and correct it. Therefore, surely if a HD DVD reads the digital audio in all of its detail then all it can do is pass it onto the cable and then the cable does the same to the amp. So does this mean that as long as an HD DVD player can process the format you are guaranteed a perfect audio source reaching the AV receiver? And if this is right does it also apply to digital picture signals? And if these are both right should we not be buying the cheapest HD DVD players?
