You do not need any switcher.
Run one or two HDMI cables from your sources presumably DVD and TV Tuner into the TV.
If you have a system remote with macros than program the remote to make the switchs for you, viola you are done.
The audio for surround is a seperate pathway, all you have to do is to switch to the appropriate HDMI input on the TV and route the audio the same way couldn't be simpiler.
