I know this has been asked a million times and I have seen threads on the same problem, but I have not been able to resolve it. When I go to tag a movie encoded with 0.9.4 x86_64 with any program it does not work. For a while MetaX would corrupt the file. Through searching I found that if I checked the 'Large file size 64bit' check box it would play the video, but no audio. If I open the .m4v file in VLC everything works fine, audio and video. I tried Vindalin (or whatever) and iFlicks with the same results. Actually when I ran the script with iFlicks it didn't add the album art of anything in iTunes, but same story...video, but no audio. Can anyone help me? 95% of the movies I have are encoded with Handbrake and from what I have searched this seems to be the common link.
