Changing permissions will allow you to make the archived recordings 
undeletable from within MythTV--but it's better to do that through 
changing permissions of the recording files rather than the directory 
(as nothing in MythTV allows you to override per-file permissions, even 
if the directory allows it).  Other than making a recording undeletable, 
changing permissions has no benefits as long as you ensure none of your 
recording rules are set to use the Archive Storage Group (meaning that 
MythTV will never attempt to write recordings to it).  By not preventing 
MythTV from writing to the Archive Storage Group directories, you will 
allow it to write other files, such as preview pixmaps, that you 
probably do want.  (You would also be able to transcode recordings 
(though transcoding will ultimately fail since MythTV will be unable to 
delete the original file, but future versions of MythTV will eventually 
be able to "successfully" do transcoding, even when they can't remove 
the original recording file).)
