It is rather frustrating. It takes about 1 second to send the change channel signal to the box, then 2 seconds of buffering, then another second or two for my STB (digital cable) to tune in to a digital channel. It all adds up to painful surfing. Fortunately, I only surf when I testing. Other members of my family (mostly my daughter) still like to surf, so they often will bypass mythtv and watch live tv directly. I have found that I can speed up the first part (sending the change channel command) by pressing Enter after the channel numbers. This tells mythtv that yes, I am done entering my numbers, so you can get to work changing channels. Myth seems to give me a very long to to enter a third digit.
