At times with this technology you just have to be a bit patient.Have had freeze problems with the HD feed since Friday.Today all HD channels were superb tuned into Sky Sports 3 to watch the IPL started great but got a on screen message saying server error switch to sony 6 to watch did that and 15 mins later tried sky 3 and all was superb.so before you start messing around with the settings just take a time out.
