But you can have different "original" encodes.

nuv is a "container" format - like ogm, avi, quicktime.  Regardless of
the content (except in the case of the hardware-encoded mpeg2 files),
the file will always be .nuv because other information is stored in the
nuv besides audio/video data.  Maybe this xml will help:

<nuv>
  <block type="other">
    <closed_caption_data />
  </block>
  <block type="video" encoding="mpeg4">
    <data>some-encoded-data</data>
  </block>
</nuv>

This is pretty much how all container formats work (not in xml,
obviously).  Isaac chose the nuv container for whatever reasons he did
(it offered him the best options).  mpeg2 is different, since it's just
an mpeg2 file with a .nuv extension - I think that was done because it's
more compatible than dropping mpeg2 data into an nuv container.

.11 myth renamed the old files to xxx.old.nuv - the latest myth simply
overwrites the old file with the transcoded one.

As far as I know, mythweb's interface is essentially the same as the
advanced recording screen.
