MP4 playback from XA40 to Vixia HF G40
 

I recently purchase a Canon XA40 and set it to shoot mp4 35mbps 59.94p. After, I took the card popped it into my old Canon Vixia HFG40 for playback using the wireless remote. The camera would not play the files even though it was set for MP4 playback. It shows the clips on the playback screen but will not play them. Any ideas.
