I thought I emailed you back -- let me double check. Just to provide an answer here in case others are having the same problem -- the only mp3s that should have that notice embedded in the lyrics section are those MP3s download from the free iTunes feed.
So my best guess without knowing the details is that you are somehow still downloading from the free iTunes feed instead of your own personal subscriber feed. I've double-checked for your account by downloading a sample podcast from your premium feed, and can confirm that the file is getting tagged with the transcript in the lyrics space: pinyin and english according to your display preferences. I will follow-up by email about this in a bit.
