2014 A4 Video from SD
 

I've tried getting video to play from my SD card with my 2014 A4 with Nav. The DVD player works fine, and I've enabled VIM. However, when I put videos on my SD card, I can't get it to play. It says it doesn't see any compatible media.

I've converted the video to 640x480, 25 fps, 2000 kbps bit rate. From everything I've read, those should work on my unit.

Does anyone have any advice for playing videos from my SD card to my 3G+ Nav unit in my 2014 A4?
