I checked my Aura this morning and see that there has been an update, I am not sure if this is just to fix the ITV-SD issue that others had or if it also fixes the COM5 freeze and black screen problems. I viewed a couple of COM5 channels without issue but that can be the case during the day and further testing this evening will give a more certain conclusion. My Aura is now on 1.00_65_241003.
