When you said that you cannot get xtreamtv pkugin to work, are you actually receiving the channels or getting a message saying that you are not authorised?
Why do you need a plugin? The xtreamtv plugin has a limited epg, if one at all. All you can usually see is what programme is currently showing on each channel. Unless the plugin has improved since the last time I used it (and then removed it soon after!) it does not provide you a 7 day epg.
All I can suggest you do is to ask your provider for a script which in turn will automatically create bouquets for you with a full 7 day epg.
