If you place your cable box sideways in the HDMEDIAPACK instead of face up or face down, it will receive signal much better. You should also check the back of your cable box or receiver for an IR Remote Input jack. With a Remote Input cable, you can extend an IR target to the front of your TV, allowing you to get great remote signal by aiming at the target. This product by Infrared Resources can be found on Amazon.com. Before purchasing, you should also check the manufacturer of the device you are using. For example, Verizon FIOS sells a remote extender specifically for the Motorola QIP-7000.
To solve this problem, set the HDMEDIAPACK to your desired tilt angle first, then place your cable box into the HDMEDIAPACK. The larger your device is in the HDMEDIAPACK, the less room you will have to align the two sides to provide tilt.
Because of all the TV's in the marketplace and various mounting options you have with the HDMEDAPACK, it is possible that a trip to your local hardware store may be necessary. Take a look at the owners manual that can be downloaded on the SUPPORT page and you will see what hardware comes with the unit.
