On checking the channels, the channels showing H264 only had audio working. Those with MPEG had both video and audio.
A second and much older LCD TV could not find the new channels.
The third TV, a Samsung worked with the new channel.
I suspect many people will be in the same situation suggesting that many people will not be able to correctly receive the new 7flix channel. The other channels which didn't work, although I'd doubt that I'd watch, are RACING.COM and TV4ME.
The problem here is the new channel is using H264 MPEG-4 that may not be present in many devices.
If when you check your TV you don't have 7flix (channel 76) run the auto tuning facility, and if the channel doesn't appear, chances are you'll be out of luck.
Update: 14 August 2016.
This issue now appears to have been fixed.
