Possible solution
To record two programs at once:
Your HP Digital Entertainment Center must have a dual TV tuner or two TV tuners
■
with the same TV signal source to record two programs at the same time. This
feature is available for select models only.
For set-top boxes that use the same IR code set, each must have its own remote
■
control sensor control cable plugged into different IR emitter ports on the IR
sensor. MC is able to direct IR commands to specific emitter ports, but all
devices plugged into that port will receive the commands.
You must make sure the IR signal that is coming from one remote control sensor
■
cable to the set-top box is not received by the other set-top box.
On an HP Digital Entertainment Center with two TV tuners, if you schedule three
■
recordings that overlap, leave one in conflict and then schedule a fourth one,
you will get a Conflict Changed error message. The program that was a conflict
appears in your conflict choices. Select Don't Record on Program Information
for the show you do not want.
Because some programs are encrypted and copy-protected from the broadcasters,
you may not be able to record live TV directly to DVD.
Your HP Digital Entertainment Center must have two TV tuners that are connected to
the same TV signal source to be able to watch one channel and record another.
If you are using a set-top box, you must have two TV tuners and they must each be
plugged into different remote sensor ports on the remote sensor receiver. Media
Center is able to direct remote control commands to specific ports on your remote
sensor.
