These days I'll only try for a maximum of 5 minutes before giving up & either watching something outside of TV Anywhere, or firing up Acestream or Sopcast if it's a must-see game. It's not ideal but I'm fed up of missing games entirely because of Virgin Media's "technology". I also tried joining the stream just after kick-off time, which is of course a schoolboy error. I got a mixture of browser just hanging or the essential maintenance message about 8 times before giving up.
Tonight isn't a massive games but the capacity issues seems to rise exponentially with the prestige of the fixture. So tonight's middle-table clash has fewer issues than, say, Arsenal v Barca in the Champions League. I'm sure if I kept trying tonight I'd get in eventually, but that isn't really the point.
