I am having a laugh.
The laughing part of this conversation is that you are selling channels that you do not own which means you restream them for £4 a stream.
Please do me a favor and place a watermark on all your channels that you own.
Re-submit a trial and I will publically appologize for being incorrect.
If you are already encoding the channels adding the watermark will be nothing more than a click of the mouse.
But if your restreaming, you will not want to re-encode all channels because your server most likley will not be able to handle it.
