The content playback does not fill my television screen.

The audio on my 5.1 channel speakers does not sound right or I only hear
audio from my rear left and right speakers.
When the DMA plays 5.1 channel files, it downmixes the analog or digital input and provides
2-channel (stereo) analog or digital output.
• On some 5.1 channel audio systems will only play on the rear left and right speakers.
• Some 5.1 channel audio systems can simulate the 2 channels to 5.1 channels, but the
sound will not be as good as with original 5.1 channel output.
13.3 Powerline Problems
V
The HomePlug LED does not turn on.
1 Use the PLA-4xx Series Configuration Utility to detect all other ZyXEL HomePlug
AV-compliant devices on your powerline network. Make sure that the network password
is the same on all of your powerline adapters. Download the Utility from the ZyXEL
website.
2 Check the DAK and MAC address for all powerline adapters are typed correctly.
3 Make sure that all your powerline adapters are HomePlug AV compliant. Check the
package it came in or ask your vendor. This DMA can not detect earlier versions of
HomePlug powerline adapters such as HomePlug 1.0 or 1.0.1. (Although they can
coexist on the same electrical wiring without interfering with each other.)
4 Make sure that the powerline adapters on your network are all on the same electrical
wiring. Connect another powerline adapter into an outlet close to your DMA’s power
outlet. They are probably now on the same electrical wiring. Check the Link
LED. If
it now lights up your powerline adapter was probably previously on separate electrical
wiring. Ask an electrician for more information on the electrical wiring in your building.
5 If your powerline network is using coaxial cable, check all powerline adapters are on the
same coaxial cable.
6 If your powerline network is using electrical wiring (not coaxial cable), check you do not
have a power meter between powerline adapters. Powerline signals cannot pass this.
