Generally the ultimo 4K blind scans quite well with the AVL6222 tuner but I have recently been seeing some issues with a few channels.
blind scan will find the transponder below okay but will not scan in any of the channels, other boxes do not seem to have an issue
There is 4 new UHD channels on 0.8 / 1west satellite as a good test for this
1 west
12705 V 45000 3/4 DVB-S2/8PSK MPEG-4 HEVC
Wow 4K, Mooz 4K, NASA and 4K Heritage
all the above are free channels
Can you please test with your VU box if you can or can not get these channels ??
Please state what box and what tuner you are using
I will add to this thread any other channels / TP's i find with similar issues.
