OK, there shouldn’t be any problem with the blank media. Verbatim is my second choice (Taiyo Yuden is first).
So let’s take a look at what you did in FCP. (I’m a Windows guy, so please fill in the blanks if necessary.) What file format did you choose for exporting the downrezzed video? Did you use FCP or Compressor?
What settings did you use for video export? Frame size? Frame rate? Bit rate?
What format and settings did you use for the audio?
