Serviio

Have a few episodes that the N100 only shows the first few minutes, I have checked on the computer and the complete episode is there and it is playable there.

So it appears that the episode is not corrupt.

Any ideas what may be causing this to happen?

thanks

What is your network configuration, do you use Wifi or wire Cable? If Wifi, could you try with wire cable?
Could you check the videobitrate of your movie?
Do you have enough space in your temporary folder?

have tried both wireless and wired
bitrate is min=44kbs, max=4544kbs, avg=1028kbs
would think that there is enough room in temp folder since I am able to play others out of the same folder.

thanks for your help...

Do you have serviio automatic refresh library enabled? Because library refresh and streaming movie at the same time could provide CPU and Network overload.
Try disabling library auto refresh.
