I have just created some vob files from a set of DVDs.
Some play OK but others there is no sound, either thru optical or HDM.
After I changed the audio setting toStere from Digital Passthtu, the sound was there.
After further investigations the file hat did not play were AC3 1 channel, the files hat played OK were AC3 2 channel.
Has anyone experienced this or know whether it is a firmware problem or not.
