I want an automatic HDMI switch to use with an Oppo BDP-83 blu-ray player. I would like the switch to automatically switch to my blu-ray player when it is turned on, then default back to a TiVo box whenever the blu-ray player is off. I do not want to have to use a remote or any type of manual switching. I have researched several different switches and most of the reviews are not clear on whether the devices will do what I am looking for. Can anyone recommend a quality switch for this purpose?
