Hi guys and girls, hope you can help with this odd little quirk I've come across.  Been using Vista MC (64 bit) for about 9 months now with several plugins like mediabrowser which I like a lot.

Went to play an episode a TV show and it's playing 3 language tracks at the same time... You have English, French and I think Italian... thought it might be the avi file itself, so tested it in WMP (64bit) and it was the same, tested it with VLC and it was fine, allowed you to select the audio track you prefered, but defaulted to track 1 which is English on all of the files. So I know it's been encoded with 3 language tracks, but I can't get WMC or WMP to play just the one, been through all the settings, have double checked the settings for the vistacodec pack (and no I'm not installing another codec pack as this one has worked flawlessly for me and others I tried caused nothing but problems ion the past).

Any ideas would be great.

I had the same problem.  I uninstalled all of the codecs I thought I had configured properly and installed the vista codec pack from shark007

everything is now working right again.

Cheers for that, I was already using the shark007 codes, but was still using the 5.0.2 version, updated to the latest version and updated the x64 part as well and it seems to have cured it.
