IPTV Stalker does work with the 00:1A:78 prefix on my 'testing' version. Still not verified if the "Token" is required to be sent to the server for the addon, or for the PVR.

PVR Stalker works with the 00:1A:78, but doesn't require the token field ... using the same credentials from IPTV Stalker. (SN, Device ID, Device ID2 and signature, empty token).
