I'm not sure it's working, I just tried the SBS of the GER POR game and after some ads (which corresponded to the websocket data):

  ...
  "text": " Every second of every game ",
  "text": " live on the big screen at Crown. ",

All that ever came back was:

  {
    "range": []
  }

It's like there were no captions whatsoever. Failing under load?

Try this link: http://beta.tveeder.com/785/byrange?&from=1402972200&to=1402...

It worked from Safari but not FF on the proxies network. During the BELvALG game there are lots of trouble again, seems to only get a small portion of the captions and then stops updating. Here is the last of what I was able to get:

    {
      "id": 4399254,
      "channel": 785,
      "text": "But at BOQ you can talk to one person",
      "date": 1403023783.284,
      "cid": 7
    }
