I've never reported this bug, but it has existed with every software version so I thought it would make sense to post it. I am using DD and every time I turn on the HR20 there is no sound. However, once I change the channel or play something from the playlist, the sound works fine. It is really only a significant issue when I want to use the buffer for a show that is on when I turn on the unit b/c I'll lose it if I change the channel. The only recourse is to watch something from the playlist for a second and then return to live TV, which is a bit of a pain. Earl or anyone else - any thoughts?
