Advanced Code for Page Down on Silver 0476 Remote (DCT 6412)

[richever]

After reprogramming some of the advanced codes on the GI 0476 remote (with a Motorola DCT 6412): http://www.hifi-remote.com/cgi-bin2/ueic.cgi?cbl_0476 , I am unable to reprogram the "page down" function. The code listed is 172. However, that number acts the same as 179, which is the replay function. Yes, I included the two zeroes. I've had no problem reprogramming any of the other functions successfully. Anyone knowing the correct code for this, or shedding any light on this topic, would be greatly appreciated.
