Comment(by markspieth):

 49 now has

 lavc fft support[[BR]]
 passthru reencode fix as found by bill[[BR]]
 consolidated gain values[[BR]]

 new configure option ''''''--enable-libfftw3''''''

 without it it uses the lavc fft. not sure but from simple tests,
 performance seems to be about the same, which confuses me as I always
 thought fftw3 was heaps better.
 perhaps others would like to test this too. I almost lean towards lavcfft
 as being slightly better (using top to measure).

 with new gain settings, centerlevel is bigger and music centerwidth has
 been adjusted to 70% to get good output from the L/R speakers.

 If anyone finds any clipping occuring in either music or movie modes, let
 me know but it shouldnt happen.

 hopefully there is nothing else wrong.

 if all gets committed perhaps some user controls for some settings from
 menu may be desirable. also continuous reencode for all modes as has been
 requested in the past. open to suggestions/patches.
