use of Reference #4

I don't see how reference #4 actually supports this sentence, particularly the part about 48kHz delivery via unencrypted digital:

"Whereas DVD-Video audio formats such as Dolby Digital and DTS can be sent via the player's digital output to a receiver for conversion to analogue form and distribution to speakers, DVD-Audio cannot be delivered via unencrypted digital audio link at sample rates higher than 48 kHz (i.e., ordinary DVD-Video quality) due to concerns about digital copying.[4]"

I've read the reference linked page twice --am I missing something? —Preceding unsigned comment added by 216.165.126.102 (talk) 19:00, 3 October 2007 (UTC)
