I have updated the software to August 18 version.
Portal loads ok.
I can access recorded content.
all TV channels display under various headings, such as sport, movies.
but none actually load/play. If I select one I have blank black screen
just to add, this happened one day after it was working perfectly well for weeks.
I am having the same issue, I tried everything but unable to play any channel, I didn't upgrade the firmware
