Carsten, thanks *loads* for the software recommendations. I will give these a go in next few days and will report back. DVDFab is available on Mac, but looks like only the Windows version supports converting from MVC 3D to side-by-side which DCP-o-matic would be able to work with. Ergh have been Mac & Linux so long, the thought of dealing with Windows makes me shudder! But hey, beggers cannot as they say be choosers. Carl - yes, I assumed lack of support for MVC in FFMPEG was what prevented DCP-o-matic from "seeing" the right eye stream. From what little I read, it doesn't sound like support is likely to be added any time soon either - apparently the MVC encoding is quite "deep" in the codec structure so adding support would require extensive changes across FFMPEG codebase. Given that MVC is pretty niche, it's unlikely to be considered worth the effort. That's the impression I got anyway. By the way, when I say DOM or VLC can't "see" the right eye stream, I mean the video plays fine in the usual way, but it appears simply as a 2D video with only the left eye image appearing. The data for right eye is simply passed over, as if it wasn't there. It isn't listed as a separate stream in DOM, FFprobe or VLC. In fact, when I say "stream", I'm using the wrong word anyway - it's not a separate stream in the usual sense, since the right eye image data is encoded as a diff from the left eye. It's more like a stream within a stream. Very unusual! Anyway thanks as ever to both of you for swift and very helpful responses. Will report back when I've figured it out.
