I just added the BWF World Championships tournament and some of the first round matches. But unfortunately these don't work in the USA because of media rights. However, if you set up your iPad or iPhone to use a proxy in a foreign country like the UK, you can watch these without problems.
In the future, I will look into integrating a proxy feature in Badminton TV itself.
For now, these videos will still benefit many who are not in a restricted country.
