Sorry about yet another post on this but I'm really going round in circles here. ALL DAY just trying to convert one stupid file!!!!! I'm not sure what it is I hate, handbrake or MKV! So I have the MKV file and its files are as below in the image. It HAS a video file and an Audio file. Both 1 hr 43 min. So, like an idiot, I fire it through Handbrake thinking it'll work. I end up with a 4 min audio file and no sound. So I read read read read read and try to fathom which of the gazilion software solutions might fix this. And about what else I can try. So I try Subler. I load the file into that and notice the audio and the video are in language 'Unknown'. Is that the problem I thought? So I try to edit. Cannot. bearing in mind this is the abridged version after hours wasted on this, I try MP4 tools. That SEEMS to make the file into mp4. VLC will happily play the original MKV and now QT will happily play the MP4. So I fire the Mp4 file through Handbrake with the ATV 3 settings. Still no sound!!!!! Any help much appreciated as the more I read on this the more options I try, the more files I create all for Handbrake to fail to deliver a file I can play in iTunes or on ATV. Jeez, if I never get a file like this to convert again it'll be too soon!!!!! NEVER again. And, if any of the software is the problem it's instant ditch. HB has never given a problem before but this file is confounding it and me. Typed before I sling the darned laptop out the window!!! What I can't fathom is why, if QT can play the MP4 audio now why does HB not simply adjust the video to ATV format and leave the audio in tact, it's already working TQVM!!! Any help much appreciated in case I encounter this again.
