Icon Question

The channel information icons show as following:

$......Box with Three Lines......Box with One Line......Dolby Symbol......HD......Network


I get teh Pay Service, Dolby, HD and Network...but...

What does the "Box with three lines" and the "Box with one line" mean??

I believe the single line indicates Subtitle and the three lines indicates Teletext.... Could be wrong.

I think that's it. I've never attempted to test either of the options though. I don't think I've ever seen the subtitle light come on on any of my receivers. The Metropolitan Opera lights the teletext light on my Openbox (haven't seen a feed since I got the Gekko), but I've never got it to produce anything other than a blank screen, and I've never seen it on any other channel.
