I also had this issue on Boxing Day (for the Spurs game). As already mentioned, I think the .tv feed was ok; it was the channel feed (think it was HD5/6) that had the problem. Hope it's sorted for today - it's just one issue after another with AJS!
I understand AJS will be rebranding next week. Does anyone know if there will be any practical implications, or is this simply a change of logo, etc? Is this related to the new STBs they're introducing?
