Locking up and resetting

well after 2 weeks of putting info and sheets on my live hub I start watching movies only to find that alot of times after I stop playback and then try to restart or resume a movie it locks up and sits there with black screen. Sometimes if patient it will restart on its own. Very frustrating after spending all that time. I think I read a post about some of this stuff but cannot seem to find it now.

I have downgraded firmware then upgraded. Seems to work for awhile. I am using iso files with a nas this setup has worked flawlessly on my wd live plus. Cleared the library all that stuff anyone have any suggestions to help Thanks


are your sheets and images made with .png files renamed to .jpg?
