Thanks for the very good example  (live one :) )

One other questions regarding MCE Remote....I have Lirc 0.8.1 that are
provided in the (K)ubuntu repository. I have problems with repeating key
strokes (e.g. navigating in EPG results almost often with 2 steps up/down
instead of 1.

I saw that there is a patch on
http://www.mythtv.org/wiki/index.php/MCE_Remote but it also says that it
should not be needed since it was fixed in 0.8.1.

Any idea??
