Generally, the way I see it is that the Watch Recordings screen is great
for "short-term" content that's constantly appearing and
disappearing--record/watch/delete content. WR becomes very much less
useful as the amount of content grows. (Though I don't archive shows, I
record far more than I can possibly watch, so I have about 1900
recordings, now, and even though many are series with a lot of episodes,
it makes navigating the WR screen challenging--and, especially, makes it
hard to find something to watch.) It also makes it hard to organize
videos--allowing just one recording group per recording and requiring
you to use MENU|Change group filter to switch groups.
Video Library (or, MythVideo) was originally designed for holding a
large archive of shows. Therefore, it works nicely, even with very
large libraries. Also, it is designed to allow user-defined
organization of the library, and to work with files, regardless of name
(not requiring/expecting a specific naming format). Navigating your
videos is easy--using the arrow keys to navigate through folders and
content--without having to bring up menus to change the view (but
allowing filtering, when desired).
So, my recommendation is for people who archive lots of shows to
consider moving the recordings they plan to keep from WR to VL. It will
help whittle down the number of recordings in WR and will result in a
much-easier-to-navigate large collection of videos.
Now that VL has great metadata support, you'll get title, subtitle,
description type information (and much more)--just like you had in WR.
Though the description will differ (from TMS's copyrighted description),
it should still provide useful information (and it's editable--even on
thetvdb.com website, if you want to help improve the description for
everyone). VL also allows you to rename video files (or, more likely,
you'll have the mythvidexport.py script rename files for you) with
human- (or UPnP-device-)friendly names instead of the
<chanid>_<starttime>.<ext> names used for recordings, which is also a
good thing if you ever lose some or all of your database.
And, there's a pretty-well-finished plan to change the database schema
to use a generic media file description for recordings and VL videos,
with only a small amount of information specific to WR or VL. At that
point, moving a recording to VL (or, the other way, if you really
wanted) would be simple--likely as simple as checking a box in the UI.
I'm hoping to start implementing those changes some time after 0.25
release (but, depending on how quickly we release 0.26, it may not be
done before 0.26 release).
