Do you know any useful tricks that are not widely known? Maybe you know how to get free movie tickets or a simple hack to improve your phone's performance. Share your tips here. My contribution: If your Direct TV is acting slow and sluggish, there's an easy way to clear the cache. Go to channel 001, press these buttons on your remote in this order as fast as possible, red-red-blue-blue-yellow-green. You should see a message on the bottom of the screen that says "cache has been cleared." I usually have to do it a couple of times before it takes and the message is displayed. You should notice a big difference in performance.
