There probably isn't a solution to this, but perhaps by bringing it up, Humax might be more likely to add an option.
My TV is not huge, and I don't have an HDTV.
I find the text giving Info about a program is barely readable, it actually hurts my eyes trying to read it.
The text only uses part of the screen, with most of it taken up with graphics, and surely the text should be a lot more important than the graphics. So it ought to be possible to use a lot more of the screen to make the text bigger.
I'm not going to buy a new TV just for this, and I don't think Humax should just assume that everyone has big HDTVs.
