David,

Regarding the VCR keys, in either TV mode or
CBL/SAT mode, you should find that the VCR keys
control either the DVD/LD device or the VCR
device, depending on which one was most recently
selected, i.e. if you select VCR mode, then TV
mode, the DVD should no longer be controlable
until you select DVD mode again.

When you say that it didn't use any programming
memory, this is true, but you are not taking into
account that it DOES take a device key, whereas
my idea does not. Using your method (which I
also use, admittedly), you would lose the DVD
functionality were you to redefine the DVD/LD key
to control some other device, whereas with my
trick you would not. Yes, it uses some
programming memory, but it allows you to do
something you could not do without it.

As for your 37 device macro, it's only sending
codes for 8 devices. That's like calling a macro
containing a single power on/off code a "100
device power on/off macro" just because there are
100 of the same brand of TV in the room. :)

My point was that...well, let's say you work in a
deparment store, and when the store opens, you
have to turn all the TVs on, and when you shut
down for the night, you have to turn them all
off. For each TV device code, you could program
it into the VCR key and use 994 to copy its power
button to one of the TV mode keys before
programming the next device code into the VCR
key, etc.

When done, you could create a macro that
contained all of these buttons, one by one,
making the store's shutdown/startup sequence just
a little bit faster/easier.

Of course, one of these codes could always be
that "ALL OFF" X10 code you mentioned, if that
was desirable. :)
