    Import of mp4(H264/mp3) drops audio track

      (I've searched high and low for answers to this)

       

      I have an MP4, created via Tivo download, decode, and encoding as MP4 (as above).  Every known player can play it but when I drag it onto Premiere's timeline, the only thing that appears is the video track.

       

      (Note, the normal Tivo decode produces an MPG bit it has embedded 608/708 captions which Premiere can't handle, so I reencode it to H264, dropping the closed captions).
