Stalker is a weird addon indeed! I got 2 boxes, an MX2 and and M8. Both using version 1.0.18, both with same custom MAC, both were working fine. Now only the MX2 works??????? lol crazy
Iptv stalker is too flakey... I use the pvr simple client instead...
Spent days pulling my hair out with the iptv stalker... as far as MAC is concerned, you need a different Mac for each box to avoid a conflict....
