But the audio now is about 4 seconds lagging the video. And I still get the "flac @ 0xaafac30]output buffer too small" when running mencoder, which I would like to know what it means, and can I fix it using mencoder. As for the editing application, it is obvious that it has serisous problems handling different audio formats. I can load a flac audio only file into the app (which is why I am trying to convert to flac), but the app gets very confused with both a flac audio and any kind of video stream. If anyone has suggestions for a good, simple editing app (trim, cut, convert) please let me know. (I will probably switch back to LiVES, even though it is very much overkill for my needs. One other thing: if I go to using ffmpeg rather than mencoder, then how do I capture from a tuner card? According to the manual, I need to set up the v4l2 parameters in another running app, before starting up the ffmpeg capture. Not quite the most elegant solution I would hope for :-(. Thanks, Carl, for the suggestion. I will RTFM some more and see if there is something I can tweak to get the audio back in sync. ken
