Mag Box Help Tutorial : Change the Buffer
This is one way to try and stop buffering or stuttering on a Mag IPTV box. If increasing the buffer size does not help, then the problem may lie with your Internet Speed / PING or connection to the TV provider.
From the Main Menu screen, navigate to Settings
Scroll down to Advanced Settings and press OK
The first line on the screen allows you to change the Buffer Size.
Pressing right will increase the buffer, pressing left will decrease the buffer. Usually somewhere between 5 and 8 should be enough.
Scroll down to OK and press select.
By increasing the buffer size, you have increased the amount of data the box will store before it starts to play back. This will result in a slightly longer time before the channel starts to play.
