I have my HR20-700 connected to my Sony TV via HDMI (the TV has DVI in, so I use an HDMI to DVI adaptor). I'm about to add a new HD DVD player to the mix. But I only have the 1 HDMI/DVI in on the TV. My choices are to run either the HR20 or HD DVD player via component or I could get an HDMI switch. What would you suggest (and if you suggest a switch, which one)?
