On our demo and reference sites, there are streaming of the matches of all leagues, you can choose and compare the match whenever you want.
I took a look at a couple of football and basketball matches that were streamed last night on your demo sites. Unfortunately, I wasn't satisfied with what I saw. I am not talking about the quality of the picture here, but my focus was only on the delay from live events. According to my tests, it was over 30 seconds for some matches, which makes the service unsuitable for my needs. Even my IPTV was faster at times.
Do you have any faster streams or do you know some particular leagues/sports where the service might be faster?
