Stalker Kodi addon vs PVR addon

[d3rider2k5]

I'm looking at donating for NFPS , however which Kodi addon will work with the donation? And which MAC address would I submit? my amazon fire stick...or the last 6 digits of my amazon fire stick and the generic first 6 digits already in the Stalker PVR addon? Searched the forums but there's no concrete mention.

You should know after using the free service for a few months. All the different means of access have cons and pros.

the free service was great on both no denying that, what i want to know is what MAC address to assign to my donation since I am using kodi? the main MAC address as listed for my amazon stick or the standard 00:1A:79:XX:XX:XX where the "X" is corresponds to my firestick MAC?

Make up the last 3 octets (last 6), if they are already used, it will fail.
