Rasplex video stops, goes back to menu

When I start a video, (SD, HD... doesn't matter)  the video will play for 5-25 minutes then freeze and go back to the movie/TV menu.  Has anyone else experienced this?

 

model B, 512MB

class 10 8GB sd

wired and wifi

version 1.37

5v, 2.1 amp PS

UPDATE:  It seems that this happens with shared content only, so it must be some kind of network setting.  I wish I knew which one :)

UPDATE: Tried v1.35, same thing.

Has no one had this issue?

I've tried 1.35-39, no good.  Can someone who is NOT having this issue gice me a bone and tell me the settings they use?

No I don't have this problem. How is your content shared? NAS? USB? PC? Does HD drop out quicker than SD?
