All credits goes to Kenny @ http://community.tub...olution/?p=5834 for coming up with a solution for the video container.
However rotating screens from landscape to portrait in various phones and tablets that I was testing. The gallery was all messed up, specifically the thumbnails. I found a couple of solutions. Try the ones that work for you.
Global Fix: This fix should work for all media types and doesn't need a specific @media attribute. Add this at the bottom of your style.css file.
I also tried a setting the entire .tubepress_container to width:100%, but it didn't behave good.
@media Fix: If you have undesired effects from the global fix, and you wanna make sure this applies to only media devices try this solution just for mobile devices.
Note: In order for me to get 3 rows of videos on the lowest setting for phones, I had to do a .tubepress_thumb{width:123px!important;}
If this doesn't work for you, feel free to take it out.
