Plex capping at 328, but only on remote access with browser

Plex basically changed the way I enjoy movies with friends, but I have a problem.

When I watch something from my local network, everything works as it should. Friends can only watch content up to 328p on the Web Browser though. HOWEVER, they can watch the content in 720 and 1080 when they use the Xbox or PlayStation Apps for Plex. What can we do for it to work like this on the browser, though?
