        The SHARC processors are for the audio decoding. HD-DVD and Blu-Ray added support for advanced audio codecs (Dolby Digital TrueHD etc) which few, if any audio processors supported. To enjoy the high quality audio,, the first players included a full audio decoder so those whose receivers could not decode the audio (most wouldn’t, unless you bought the receiver that year or afterwards) could use the analog outputs.

        Also, HDMI was fairly new at the time so if your receiver did not have HDMI, you needed the analog outputs to enjoy the high quality audio. You could, of course, use the lower quality optical/coax digital outputs, too, but one big reason for the HD formats was the higher quality audio.

        The M-Systems flash module (DiskOnChip) is actually a USB 2.0 flash drive. It plugs into a standard PC motherboard USB connector. You can make an adapter cable or plug it into a PC and see it as a standard USB flash disk. Since it runs Linux, you need a Linux PC to read out the software.

        The main player software is encrypted with the key being the serial number of the HD-DVD drive. Windows does recognize the drive properly.
