Sound only on left channel, wanting to duplicate audio on right

[justme]

Hi
I found the post listed below.  It helped me get the audio from the left on both channels.
However, when I output the video (used to be MPG) it outputs to .AVI and doesn't play via Windows 10 or VLC.

Just trying to figure out how to output the video along with the two channels into MPG.

Thanks!
Jim

PS - Very cool tool!!

You couldn't miss the output format dropdown list, could you?

Audio filter : Mixer -> Stereo should do the trick
