questions about recording audio

Three questions about recording audio:
> 1. Support for new compressors?
The recordCompressorTypes property returns a list of available
compressors that includes items (like MPEG-4) which are not shown in the
"answer record" dialog.
Since the "answer record" command calls QT to bring up its dialog, why
aren't all of the available compressors shown?
> 2. How to determine format/compressor compatibility?
The docs say:
Not all sound file formats are compatible with all
supported codecs. If you try to record sound using
a recordCompressionType that is not compatible
with the recordFormat, the compression type will
be changed automatically to a codec that is
compatible with the specified recordFormat.
How can I determine which compressors are available for which formats?
> 3. Updating options in the "answer record" dialog
If I change the recordFormat and then call "answer record", it always
displays the same list of codecs.
Is there a way to have the "answer record" dialog only show options
relevant for the current recordFormat?
