movie maker crashing maxx hd repeatedly

[nepkp]

I was editing some videos on my maxx hd, and watching via HDMI out to my tv. Crashed when I got to about 3 minutes of timeline, crashed when I played it, crashed when I exported it crashed after watching the exported video, also no video out to HDMI after crash, had to power phone off and on.....is this common? I was using the movie maker that came with the phone.
