Comment 9 for bug 573607

@madbiologist: what's a "problem file"? Please, specify that, and I'll provide it. Also, I'm not sure the linked bug is really a duplicate. It doesn't refer what the missing codec is (OK, perhaps it does in the screenshots, but I can't read them), it refers specifically to audio and subtitles, but not to video, and was closed because it was lacking necessary information to debug the issue.
