3 tv's in one room

[QElliott17]

Ok, so I realize this is overkill, but you only live once. I am currently looking to add 2 tvs to my HT. I currently have a 73' dlp with blu ray 7.1 system, directv, xbox 360 and wii hooked to it. I would like to add 2 tvs both with access to the blu ray player and xbox. In addition, i want to be able to watch tv indepently on the 3 tvs (e.g. 3 different football games). I see there are hdmi matrix devices that would achieve the switching what is already hooked up to 3 tvs. Most hdmi matrix devices are 4 x 4 that are reasonably priced. Do I need an 8 x 8 matrix? Can I use the 4 x 4 to connect the blu ray and xbox 360 to all 3 tvs and then independently connect 2 directv boxes to the other tvs to get different channels on all three tvs? Thanks
