mitch26 Posted September 24, 2009 Posted September 24, 2009 I can watch ARTE HD in German AC3, German stereo or French Stereo without any problem but when I record, the playback is correct only for the German AC3 audio track, the other two audio tracks are mute. There is no problem either with ANIXE HD and therefore it seems that it is a multilingual channel problem. Any advice ? Quote
ml 05019 Posted October 4, 2009 Posted October 4, 2009 Confirm this on a non-HD TV: if a channel has several audio tracks and some of them are mono and some are stereo, the mono audio tracks are mute in the recording. Quote

Thanks for your advice but this is not the cause of the problem, playback of multilingual recording is OK on non HD TV channels. Since my last post I found that i can playback all HD TV multilingual recordings I make from ARTE if I use the DVBViewer application instead of VLC media player that I was using previously. Quote
ml 05019 Posted October 4, 2009 Posted October 4, 2009 (edited) The question is not about HD or SD channels, but about whether all audio streams of that channel in question are in the same format (AAC/MPEG audio, mono/stereo/5.1). If they aren't the same - and I see they aren't: German AC3, German stereo or French Stereo this might be the reason of your problem, too. Edited October 4, 2009 by ml 05019 Quote
Tjod Posted October 4, 2009 Posted October 4, 2009 What are you using for playback? Try DVBViewer with AC3Filter as audio decoder. Quote
ml 05019 Posted October 4, 2009 Posted October 4, 2009 (edited) As I don't have any channels with AC3 sound (I only have channels with stereo and mono sound for different languages) I believe it isn't the problem about AC3 itself, but about the format in which DVBViewer records the audio streams. I tried to use standard Windows decoder, as well as ffmpeg and ffdshow to play these videos, but there's no chance - those audio tracks, that are not in the same format as the first track, are just mute. If you want me to, I could upload such file for you to analyze Edited October 4, 2009 by ml 05019 Quote
Tjod Posted October 4, 2009 Posted October 4, 2009 ffdshow has a problem with mono. 1) install AC3Filter http://ac3filter.net/project/1/releases 2) Options > DirectX > Audio > select AC3Filter for MP2 Audio and AC3 Audio 3) play the recordings in DVBViwer Quote
