How to Convert mp4 or mov files to avi for epson projector?

I am running media encoder on a mac. I have an .mp4 file which is also available as a .mov file but I need it to be an .avi file with linear PCM codec so that I can play it from a thumb drive on my projector. I used a converter to convert the file to .avi but it still doesn't play on the epson projector.

Can you help me achieve this?

There is no .avi option in my premier pro or the media encoder.

Thanks

Sue
