Thank you for the file, tiny_psnr says it is nearly identical to mplayer 
baikonur_r7_overflight.mov -ao pcm -ac qdmc (stddev: 0.01)
Original entry to FFmpeg_Wishlist was from 2007-08-26 without sample.
I tested ffmpeg r5415 (2006-05-28) with tiny_psnr (always baikonur sample vs
binary decoder):
stddev:  473.69 PSNR: 42.82 bytes:  2850816/  2850816
The only relevant change was r16865 (2009-01-30), the current values are:
stddev:  260.64 PSNR: 48.01 bytes:  2850816/  2850816

The log message for r4724 contains a link to a possibly more useful sample
(uploaded to incoming/issue214), I also don't hear much difference for the
helicopter sound.
