Hey there, i got your PM too, but ill respond here. As for the SMplayer not starting, make sure you let it install in the default location. Also, i would suggest installing the version of SMplayer that was specified at the beginning of this thread. Make sure you you get the SMplayer stuff working first. As for the errors returned, it might have to do with that its not detecting any software trying to initiate the stream.. Thats why i suggest getting SMPlayer working.
Also, even though i wrote the program, i have not used it in well over a year. I no longer use my Amiko STB. I wouldn't think amiko would change anything on the Big2small server, but then again, their might be subtle differences that might make it no longer work. There might be other users here that can chime in.
I can tell you when i originally programmed it, i ran a TCP sniffer program that i installed on the android so that i could watch exactly what the Android program was sending to the Amiko and what response were getting returned. I was then able to replicate that to make it work in this windows program. If the Big2Small android app still works and it hasn't been updated in years, then this program should work too.
