Hello, I am wondering if my co-star remote and or control unit is defective or just not powerful enough. The remote has considerable delay/lag and I am only 10 feet away from the unit. The Vizio remote is only usable if I am within 4-5 feet of the unit. When I try to use the keypad of the remote and type on it, their is a delay on input of the text but when it finally shows up on the screen it types the same key multiple times.. For example if i'm searching for the term "dice" it will lag and type out "ddddddddddddddddii" etc.(This is with me taping each letter once*) I unpaired and paired the device, I've attempted to turn off my router/microwaves and even cordless telephones to see if that was causing interference and the remote *still* lags. Any ideas? its almost worthless.
