Default HTC Media Link HD issues

I just bought a media link hd so I can use my phone wirelessly in my jeep. Seems to work properly but I'm having an issue streaming video. I'm only able to mirror my phone but media link is supposed to allow you to play video on second screen while using your phone for normal use. Same issue @ home connected to tv. Not sure if this is a rom issue or issue with the One. I'm on Stock With Goodies 5.5 v1.42. Also I used it with my wife's Evo 4g LTE & does what it's supposed to do. Please help, I really want this to work without just mirroring
