For IPTV Stalker Papaio, I hard coded the first three pairs to 00:1A:78 to enforce the rule that users not use the 79 prefix in non-dedicated STBs and apps. If you had read the OP on the release thread you would have seen that. It's remotely possible to use your AVOV's MAC on this addon, but I'm going to assume that you shouldn't be one to try this for a number of reasons.... it won't work.
If you want to use this add-on, you will need to use a different MAC starting with 00:1A:78, and use the last three pairs of that mac, and if using the same donation, you will need to do an IPTV Reset each time you switch between the box and this add-on.
