Can't remove default app setting
I have a Nook NT 16gb, rooted, stock firmware 4.3 running fine. My problem is I can't seem to clear a default app setting. For example video, it is currently set to the B&N my media app which I did accidentally (it originally asked me which one). Well now I can't remove it. I go into the nthidden settings/applications/all/mymedia but it doesn't say it is set as a default. When I KNOW it is, when I click on a movie in question it fires up the mymedia instead of one the other 3 installed. I tried the clear defaults but nope no help.
Oh I also tried the "default app manager lite" in the google play store, but nope that doesn't show any defaults set either.
