Very few audio codecs are patent free.  That's life.

It's not a good idea to use musepack in any container.  It's not a
normal, packetized format, though that seems to be planned.

FLAC is lossless, meaning your audio will be huge.

You can't get better quality than keeping the AC3.  If it takes too much
space, you can try other codecs, but very few are efficient at encoding
more than 2 channels.
