I'm finding it more and more difficult to find IPTV providers for my MAG256Wi box - I have contacted the manufacturers (Infomir) re this matter, the audio on vod being a major issue it seems, as some films play and others don't (i.e. no audio but great vid) - think it's to do with codecs being used?
I still find the 'Live' channels are great - better than, say, Firestix - IMHO.
