TV or stereo remotes (not just the Terratec) in general will usually
be not as responsive as remotes made for computers. The former usually
transmit the same signal again and again in given intervals. A press
can only be considered to have ended once no identical signal has been
received within that interval.
So, if that interval is f.ex. 0.5 seconds, the receiver will have to
wait until around 0.6 - 0.7 seconds have passed before it can tell
that you have stopped pressing a button on the remote.
If you need more precise control, you can also use an Apple Remote
with the Cinergy T2, EyeTV and Remote Buddy.
I can't really say much on the range of the receiver/remote
configuration. I didn't do any experiments with regards to that. What
may considerably weaken the signal, though, is if you should have any
kind of film on the receiver or remote (the protective kind of film
you find on new electronic products).
Best regards,
Felix
