ProfQuill put up some screenshots of hidden screens on Post #539, here:http://www.avsforum.com/avs-vb/showt...2#post15255082
I use 5 hidden features:
-Extended EPG (16 day capability, I've seen 7+), which also lets you access the Program Detail screen (my stations give me a lot more text);
-Frequency, PID and 'sticky' signal meters screen;
-Program Timer Menu (one click to event timers);
-One button toggle for sleep timer;
The EPG is not a thing of beauty, but I will put up with military time to have it. The full program detail font is vastly easier on the eyes than the CM7000's. Zat doesn't have detailed program descriptions except inside the hidden EPG screen.
Look for the long number below the bar code -- the underlined 4 digit code, has to be 0830
or lower for the hidden EPG. If you have a 12 hour clock instead of military time, you have the version without the hidden EPG. Retailers stopped selling the early version months ago, though, so you're probably looking in the used markets for one.
