audio/commentary only comes from one side

[curlyky]

I've noticed some problems with my videos that i don't know how to fix

I make videos and often watch youtube using the youtube app on playstation, so this is where I found the problem (somebody also told me they noticed it)

To make my videos I'm using a hauppauge hd pvr rocket plugged into my ps4 and to record my commentary I'm using an audio technica at2020 xlr (which is plugged into the microphone slot on the capture card) I don't have the capture card hooked up to a computer instead I take the files I recorded on my flash drive to the computer for editing later on

I'm using windows movie maker to edit. Also a little side note, because I am able to plug the microphone into capture card, the captured card records my commentary and game play as one file.

So the problem is here, it took a while to notice because when editing on pc everything sounds fine, but I went to check my video on ps4 (youtube app) to see if it turned out okay, I noticed right away that my commentary was only coming through one side of my headphones and the gameplay was only playing through the opposite ear, which was weird because when I went on my computer and went to youtube (not the app) to check it, the audio seemed fine and how it should be which is more mixed in audio rather than hearing a voice in one ear and a game in the other.

One more thing, I checked the file properties and it says that audio is set to stereo,

Can any one help me to fix my problem? I just want to create the best viewing experience I can but knowing the audio is messed up like that when my vids are played through youtube app is kinda ruining it
