(This needs some cleaing up of the grammar, but that's beside the point
right now.)

Somehow, this changes the stats while running. I no longer see the
overall stats. If I map video first, I see only the video stats, but it
seems like the audio stats flicker through. If I map audio first, I see
a duplicated line (extended), which shows video and audio stat lines
side by side.

I don't think this is what you intended. You only wanted to show the
*final* stats differently, correct? If it is intended, I'd like to
point out that the status line does not have enough space on most
screens to hold twice or more of its current content. I would still
like to see overall stats, also at the end, because it says something
about e.g. the total size. In the summary report, per file and per
stream stats may be nice though.
