I've done the play thing with the DVD player, added pauses in macros, and played around with positioning. I have yet to find a place where the red status light isn't flashing if even faintly.
More tweaking is definitely required.
This is key. The red transmit light needs to be off unless you are sending commands from the remote. Try rotating the base station 90 degrees, adjusting the antenna, moving the base station to a different shelf, etc. until the light stays off.
