You should not give feedback on issues that you do not understand at all, it's of no use and irrevelant. The problem you are having has simply nothing to do with the code itself. I'll try to explain, but this will be the last time I do so read carefully. 1: That is because your LAN speed may be up and over 100 times as fast as using an outside connection. Ofcourse it is smooth. LAN speed depends on your network adapters speeds. How fast can your server upload, and how fast can your client machine download. CPU speed is a factor aswell, because you could have enough network speed but if your PC is too old, it can't transcode the video well enough on the fly. 2: 3G speed is dependant on a lot of things. How good reception do you have, how many other people using the same link tower your phone is connected to, and naturally what your dataplan speed is. Knots wasn't designed to go well with 3G and other outside the house solutions (Direct quote from ukkis opening post here: "Tired of transcoding and copying music and videos to your tablet just to view them at bed?"), although if you know what you are doing, you can create transcoding profiles that give you bareable quality and unlaggy playback, IF you have a well working 3G connection on your device. Things that are important on slow connection speeds are low bitrates and higher buffering. 3G can at best circumstances just be so slow that there is no point trying to use Knots for playback (if your dataplan speed is too slow or reception isn't good). 3: Again, depending how fast your internet connection is (upload stream is the most important factor usually), using the servers outside IP in LAN makes the stream pingpong via your ISP and thus using whatever DSL/Cable etc speed you are paying for, instead of direct local area net speed. Now really, it is not anyone of our job to tell you these basic things, I don't want to be rude and I just wrote all this to clarify so the thread could stay cleaner. If you still have problems with networking, you should resort to finding info elsewhere.
