Has anyone else had issues with the on demand service using up all your Internet Data usage allowance? On Thursday of last week I attempted to watch Batman off the HBO On Demand Site. I noticed Friday evening it was still downloading. I didn't know it was even downloading because it had started playing when I started it. I got an email from Cox stating that my usage for the month had gone over When I looked at the meter it showed 80GB used on Thursday and 160GB used on Friday. I called Cox to figure out how that happened. The first question the rep asked was if I had tried to use DirecTV on demand. Since then I have not used any of their on demand services and have streamed through my Roku player for hours at a time with barely any usage. Does DirecTV have a flaw in their on demand system or did I do something wrong? I have the little internet deviced hard wired into my Router. Thanks in advance for any insight.
