Well, the glass is undoubtedly going to absorb some of the IR, but you'd have to be particularly inept in designing a cabinet to use glass that was heavily absorbing at remote control wavelengths. But it's not impossible....... I use equipment inside a glass fronted Hi-Fi cabinet without problems, but it is a thin sheet of plain glass in a wooden door, not the thick smoked glass of some TV stands.
There are a few other things to look for:
a) make sure the glass is clean, the fine layer of dust that accumulates near TVs won't help.
b) direct sunlight or flourescent light (esp from energy saving bulbs) falling on the sensor will degrade performance
c) your TUCTH100 is new isn't it? Check you've removed the protective plastic film from the display. Some of those absorb IR.
That's about all I can think of, except an actual fault. As I said, my machine responds quite quickly to channel change requests. Other operations can be slower though, particularly if they involve HD activity. The machine seems to do the activity, then put up the onscreen result, rather than give an immediate on screen indication that the command has been received, and then go off and do the activity.
