It looks to me like two of the three tables were just moved from one
place to another, if i'm understanding the patch correctly:

 http://duke.edu/~mgg6/rockbox/tremor_ffmpeg_imdctv2.patch

revtab appears to be the only new table.

I'd be interested in applying a patch which has the properties Mike
describes to the version of tremor i maintain in debian, if it was a bit
cleaner relative to the main sources.

when i try to build it, though, the build fails with:

maybe the patched makefile is missing something?
