I have a Motorola DCT6416, and when I press the power button on the remote, it takes anywhere from 30 seconds to a minute to actually power up. When I want to change channels, it takes 30-45 seconds to actually change the channel. If I try to go back on a live recording, the screen just freezes for a minute or so, then it never actually goes back when it unfreezes. I've reset my box, and I have new batteries in the remote. Any suggestions??
