ec76ef5ae2 fate.txt: replace FATE rsync command with a make command
Remove reference to the mplayerhq.hu rsync command, and replace it
with a reference to the make fate-rsync command.

rsync needs still to be enabled on mplayerhq.hu, and it is currently
not working. Also the fate-rsync Makefile target can be easily updated
without the need to keep the docs in synch.

7f3a7b5c40 ac3enc: add channel coupling support
Channel coupling is an optional AC-3 feature that increases quality by
combining high frequency information from multiple channels into a
single channel. The per-channel high frequency information is sent with
less accuracy in both the frequency and time domains. This allows more
bits to be used for lower frequencies while preserving enough
information to reconstruct the high frequencies.
