I have had my XRS4900 for a while now but have never been able to get Live TV, VOD, or REC to work. I don't think I know how to setup the Server settings. On the MAC Server, I've tried typing in my Server ID # starting with 00:1A...... in the portal URL after the Http:// and I get "Invalid server URL". What am I doing wrong. I thought the Live TV came with the 4900 but I could only get a subscription IPTV to work a M3U Server. Any thoughts would be appreciated.....
