Add two more media Queries for a total of 6

I guess this has kind of been done to death here above, however the only reason i am looking to be able to separate an ipad landscape media query from desktop is because I am building a site with a video background (following @danro 's instructions over at how to add a background video), and this doesnt work on ipad obviously. so i can set it use the video on desktop, and replace it with a static photo on ipad portrait, however means that anyone viewing the site on ipad landscape will get something that doesnt work unfortunately. Not sure how best to avoid this problem without abandoning the video idea altogether.

Assuming theres no plans to add this query as @thesergie suggested, any suggestions welcome.
