We have decided to replace our Toshiba DVD Recorder with TiVo with a Intel Core Duo Mac mini. We don't have a video source connected to it, so it is only used for playing DVDs and listening to our music collection.
I want to connect the Mac mini to our TV though DVI, but our TV only has one HDMI connection. So a while ago, I saw this post that mentioned a 2-port HDMI switcher, for less than $100. Unfortunately, it looks like this has been discontinued.
