    I'm trying to record content onto my iBook from a Motorola digital hd cable box via firewire (through a program called iRecord), which gives me a .m2t file. I am able to play this file in VLC media player with both audio and video present, so I know everything is there. I then want convert this to a format burnable to dvd.

    Enter ffmpegX. First I should probably mention my installation. MacOSX distribution, obviously. When I install ffmpegX, I downloaded the three extra binaries as instructed onto my desktop and left them as zipfiles. I then selected them via locate and clicked install, and all seemd to work just fine. I am able to access the program. It's worth mentioning that on successive runs of ffmpegX, I am again asked to install 2 of the 3 binaries (the last two). In the install guide on the website, it says to download this zip file and unzip it. I have tried downloading the zip file (containing mencoder and mplayer and located here http://prdownloads.sourceforge.net/mplayerosx/ffmpegXbinaries20060307.zip, btw), but whenever I try to decompress the file I get a source error and no decompression appears to take place. Perhaps the file is corrupt? Anyhow, I still seem to be able to get into the program.

    I select my .m2t file for input. Immedietly the source format reports...
    From: MPEG-TS
    Video: mpeg2video, yuv420p, 704x480, 15000 kb/s
    Audio: No audio

    I select DVD ffmpeg (my goal is to burn this to a DVD) for the target format which reports...
    To: DVD
    Video: ffmpeg mpeg2, 720x480, 4000 kbps, 29.97 fps, no crop
    Audio: ac3, 48000 Hz, 448 kbps

    I click on Encode, and the the process takes no time at all. If the source file was called foobar.m2t, the encoding produces a file called foobar.m2t.ff.mpg.. with no VIDEO-TS and AUDIO-TS folders produced as apparantly expected (in order to produce a DVD burnable format). The file size of foobar.m2t.ff.mpg is 0kb, leading me to think no encoding really happened at all.

    The encode log reports the error: "Number of stream maps must match number of output streams"

    My questions include,
    * Why is Audio reporting No audio in the source format section?
    * Why is a .mpg file being produced when I expect the VIDEO-TS and AUDIO-TS to be produced?
    * Why is the size of the produced file 0kb?
    * Does anyone know what I'm doing wrong?

    I would really appreciate some help here.

    Thanks,
    ende

    ffmpeg didn't detect an audio stream, hence no audio reported.

    The conversion process goes in steps: first create a DVD compliant .mpg file, then author a VIDEO_TS folder from that.

    Because the number of stream maps didn't match number of output streams. Video-only input can't create video+audio output. This error stopped the conversion process.

    Try getting mplayer installed correctly, then try the Play button in ffmpegX, which uses mplayer to play your source file. Maybe mplayer will succeed where ffmpeg failed you. If mplayer gets audio from your source file, then mpeg2enc should be able to convert your file to DVD. Use the DVD mpeg2enc preset, with mplayer selected as the decoder in the Options tab.
    Also look for the audio details in VLC. Menu Window>Information>Advanced Information should list the streams. Open the stream information by clicking the triangles. Under Codec it should list the audio format.
    About installing mplayer/mencoder: Check the file size of the .zip archive. It should be 15119081 bytes. If it's smaller, then your download was not complete.
