Well, with the help of my father it was just SMB Share.
First what I did is go to \nadrive and picked my share folder (in this case the share name is ‘gab’)
The only thing I needed was the share IP which was different than my computer.
In other words, yeah it was an SMB Share and for the first time I played video file with no lags, nothing.
It’s interesting because I try to play videos from my nasdrive and it takes a while in my computer but for the WiiMC its just a couple of seconds.
