Was never a problem for me. Even when I did have an issue with my
channel changes (due to the IR transmitter hardware I was using), I
modified the "real" channel change script I was using to provide locking
and synchronization (to ensure each channel change finished before the
next started) and logged the output--thinking that may have been causing
the issues. From the logs, I determined that there was never a
situation where the locking/synch code ever provided any benefit (i.e.
even without it, there would never have been an overlap--even when I
tried to trigger an overlap I couldn't).
But, hey, whichever you want to use--after all, why wait until you have
a problem to write code to fix that (non-existant) problem. ;)
