Hi, has anybody come across this? I have a few mkv files that are ripped directly from blu-ray that play at twice normal speed with the external player. This is one example. This mkv is ripped from the UK version of the Criterion release of Cat People (1942). If I pick the second audio track (AC-3) it plays normally, but if I change to the first (PCM) track, it plays back at about twice normal speed.

Hi ! Same problem here ! A mkv file from the Criterion (!) film "Ivan's Childhood" plays 2 times faster than normal... Any idea anyone ?? Sound is also PCM like in GarryT's case...
Thank you! I was beginning to think it was just me. The problem is with the external Zidoo player and only seems to affect files with mono PCM tracks, which are fairly common with Criterion releases. The internal XBMC player will play the files at normal speed, but without any audio. I managed to get round it temporarily by adding VLC as an external player, which is fine, but hopefully there will be a fix for this.
Ok. I will try this way... Thank you ! My problem is with a stereo PCM file with the internal player... So I think that the PCM management is just a mess... Althought I didn't try yet to go through the many possibilities of changing the audio parameters to fix it. ; )
Same problem when playing mkv and selecting mono LPCM using the Home Theater 2.0 app on firmware 2.0.34. 2 channel LPCM and other tracks play correctly. Tried adjusting various device settings but couldn’t get the 1 ch audio to work correctly. Anyone know how to convert 1 ch to 2 ch?
Just got mine fixed. Use mkvtoolnix to save the mono pcm from the .mkv as a .mka file. Use Pazera audio extractor to convert and save the .mka as stereo .flac. Use mkvtoonix to combine the .flac and original .mkv file as a new file. Deselect the mono pcm in the original .mkv when you do this. Mkv with the stereo .flac audio plays at the correct speed.
Interesting. Thanks for the info. I'm not familiar with Pazera, but I'll give it a try. Hopefully this will be addressed by Zidoo at some point though.
