This is a version of the HD20.bin which has been modified to fix the dreaded Channel Change Error - also known as "Please update the newest SW" nag.
The expiry date has been extended to the year 2028 (s/b long enough ?).
Used the HD20.bin so that we can tell immediately if the old expiry date of Jan 30th 2012 is fixed.
The HD20.bin has the same functionality as the HD21.bin just different expiry date.
The original HD20.bin included a new channel list.
This channel list was removed from the modified bin - did not think it was useful.
