When you change to channel 5 then the system has to start buffering video on that channel. There's no way to buffer more than one channel without multiple tuners and even then it's pretty difficult. Besides, who's to say what the additional buffered channels should be? If the system is buffering channels 4, 5 and 6 on the three (hypothetical) tuners available and you jump to channel 57 you're still gonna have to wait for those 3 seconds to start buffering that channel and now you've just wasted the time/CPU/disk space that you were using to buffer channels 5 and 6. Make sense? Brad
