I'll give your script a try, but in the mean time, maybe you can clear
up some confusion for me. I had the recording use the Autodetect
transcoder. I'm actually transcoding the recording that I want to
archive again now just to see what happens. I guess I'm not really sure
if I need to change anything in the Transcoder settings, or transcode
the recording using another transcoder before archiving it. I won't
archive every recording, but if I think I might want to, I could set it
up to record using another one other than Autodetect.
Thanks for the help!
