Version 6.84.2 still problematic with AAC audio, but can open 90% of the channels that use this coding. Trying to open the problematic ones, can freeze Progdvb and sometimes even Windows

.
Another old issue with audio, you can see in this picture:
Data channels seems to be decoded as audio channels, i guess it should not be, as that may cause problems.
About data channels, there´s something crazy in Progdvb: they cant be hide in channel lists, but video and radio channels can be hide

.
To me, think its better allow to hide radio and data channels, and dont allow hiding video channels
