    I'm trying to take video files from EYETV, export them as "MPEG ELEMENTARY STREAMS", and then use ffmpegX (VER 0.0.9y) to mux the .mpv and .ac3 file - which I plan to use "BURN" to create a "DVD (UDF)" project for burning to a DVD. This process I found at http://forums.macrumors.com/showthread.php?t=245426 - posted by "Revlimit Punk". My issue is this: When I get to the mux portion of ffmpegX, there are always failures. I have done some searching around in these forums, and I can't find anybody using MUX to do this on ffmpegx....

    **ERROR: [mplex] MUX STATUS: Frame data under-runs detected!

    Any help would be greatly appreciated!!!!

    1/ I'm not sure what, if anything, you can do about frame data under-runs, except try other software for the same procedure.
    2/ Can't your EyeTV software save as 'MPEG Program Stream'? Then it would already be muxed.
    3/ You could give MPEG Streamclip a try. Open the .mpv file. MPEG Streamclip will find the .ac3 audio file by itself, if it is located in the same folder with a matching name. 'Convert to MPEG' will take both elementary streams and mux them as an .mpeg file for further processing.

    EYETV will allow for export of MUX'd Stream, but I don't think I would be able to burn the resulting file using the "UDF" format. I will take a look at mpeg streamclip. Thank You!
