any one know a good audio switcher for promedia ultra for a computer, tv and dvd. that can support multiple types of input and out put.

I use an Impact Acoustics [Cables to Go] 6x2 component video matrix. I do not use any component video connections but I input 4 optical SP/DIF and use the the two output for input to Klipsch DD5.1 and Pioneer wireDolby headphone decoder/transmitter. I upgraded to this unit when I bought the Pioneers from an Impact Acoustics three-way switch, which I previously used for component connection of Comcast settop box and Panasonic DVD recorder to my previous HDTV/monitor. I might still have the three way switch if you are interested.
