Comment (by JohnGalt):

 Great on the patch!

 My point is that -f m4v, -f mp4 and -f ipod should all allow TrueHD, DTS
 Master, and DTS audio streams to be included and not error out like it
 does now.

 i.e. -f mp4 won't allow DTS even though it's clearly supported by the
 standard and -f ipod is just moov atom optimized and should allow the same
 options as -f mp4 as should -f m4v

 It appears that the artificial blocks in the code that are stopping these
 from being included need to be removed as if you dance around them you can
 get it to encode them in mp4 files and they work fine, but it should just
 do it without having to jump through hoops.
