Currently trialling https://www.fastip.tv .
Very impressed with the logical grouping of channels, and most of them are available in SD, HD, and FHD, so usable with different Internet speeds.
For the F1 fans, this service has the F1 TV channels as well.
Minimal buffering on the UK channels, plenty of other EU channels, good EPG.
I like this service a lot when compared to other ones, especially since the inclusion of Italian, German, and Spanish sports channels, there are multiple redundancies for watching F1.
Any images of the EPG layout / Channel grouping?
