it would be to your best interest to learn how the m3u Playlist option also works. Then you could have your MAC attached method with it's server EPG source or also could switch easily on that Buzz box to a Playlist method, which could have 2 sources (Acid's and Shooty's).
That way you'd have 3 possible epg sources to choose from easily.
The initial setup will take some time, because you will have to create Playlist portals and also be able to quickly log on service site and switch from MAC to no MAC
I can help you with all of this but I won't get into it just now. The guides are posted.
But if you want, I can direct you to correct info so you can then do the work
