I allow myself to insist because I have a friend who has the same equipment and it works at home, if I record sat so it's ok.
On an Uno + with openpli6 iptv
I can not record the iptv stream, I explain the recording starts the folder this creates correctly on the internal hdd (I reformatted it to see, but no result)
Once the recording is done, the file is clearly visible, etc. But at the bottom left of the screen we can see that the file remains at 0 mb so empty
Here is a picture of the situation we see the 2 .ts files and the .ts.cuts which indicate 0!
