avi stops playing

Hi, just got a new TV (Samsung UN40D5500) and installed Serviio today. Everything works great except when I am watching AVI files, it sometimes stops and returns to the Serviio menu. I fast forwarded back to the point where I was just to have it happen again shortly after. I'm sure this has been discussed before but I wasn't able to find any threads referring to this issue. Thanks in advance for any help!

might be a dodgy file or your network (are you on wifi?)

Thanks for the quick reply. Nope, I'm using a wired connection. Right before it stops playing the picture lags a little then it stops completely. I'll try with a different file and see if the same thing happens.
