Can you provide (or point us to) an explanation of where you think
Video Library is going?  Right now, I don't have a good sense of
why Watch Recordings would even be its own separate interface---
if Video Library provides superior organization, why does (or will)
WR exist at all?  It seems like it would just be a different UI
presentation of the very same data.  Am I misunderstanding it?

Is any data or metadata lost when moving something from WR to VL?
Does Myth forget in any way that it's recorded the showing, or does it
forget metadata like who's in it or its original airdate or whatever?
Do recordings in VL consuem fewer DB resources (for those with big
DB's), or is there less per-recording schema updating work when
upgrading MythTV?  Is stuff in VL still commflag-skippable if
it hasn't actually been cut?  Etc.

Put another way, is there any reason not to automatically move
-everything- from WR to VL if VL is (or will be) so good?  Right now,
it seems like there's an artificial separation; this made sense back
when MythVideo was "the place to put things that didn't come in
through a capture card" or "the place to rescue your orphaned
meta-data-less recording", but given what you say above, are WR and VL
not the same thing just because they haven't been fully merged yet?

One reason I ask is because I will at some point have a very large
migration from old Myth to 0.25, and one question might be whether
everything archived should then immediately go into VL, leaving WR
empty except for recordings-currently-in-progress...

Thanks.
