For some reason, when watching my Slingbox, the picture is stuck in 4:3 on the web player. On my iPad, it's really bad quality even though it has a good connection. I'm thinking the low quality is on the iPad is related to the 4:3 issue. Nothing has changed settings wise the past few months, and the problem just started a few days ago. Picture is correctly displayed when watching TV directly.
