Greetings,

I have an AV-2100 and I'm using it to control
an Apex AD-600A DVD player. I had to "learn"
all the necessary commands from the DVD remote.
I've created a macro to turn on my amp and
switch to the correct input. Ditto for the TV.
The only problem is the DVD player will not
respond to the power-up command in the macro.
It WILL activate if I manually hit the power
button on the AV-2100, just not as part of
a macro. Since it does respond to a manual
key-stroke, that means the "learned" power
on signal is correct. I've got the timing
on the macro sequence set about as long as
possible. Any ideas?

Try re-learning the code (just pressing, holding, etc).
