Both those channels are working fine for me when chosen from the guide. It could be a memory issue on your device. Have you cleared cache from your device settings? You could also try using one of the English files (NFPSF1 or NFPSF2) instead of the Full (NFPSF3 or NFPSF4) to see if that helps. You'd also need to clear your guide data for changes to take effect.
Doing that indeed fixed those channels and now my Guide is fully coloured BUT... Now the PPVs and other channels disappeared again!!! What is causing that to happen so often on my end? This is so frustrating, it's like the 4th time that my PPVs and other channels disappear from my guide, and this time all I did was clear data from live tv > general and clear data from guide.
