Mini Freezes during Hulu Playback

Often during the last 3 weeks our Mini has been freezing during playback, Eg playback stops, the spinning circle in the upper left appears, then stops, and the unit is unresponsive to further button pushes. If I unplug the unit, wait a minute, and reboot, eventually everything seems fine. I have not observed this in live TV or playback, so at first I though it was Hulu, but since everything freezes once it goes, it must be mini.

Any thoughts or suggestions? I tried the search function...
