I hated my once-upon-a-time software manager for his anal insistance on a SDD (software design document) but how I miss one for myth. There are clever people working an myth and I find the gestalt overwhelming.

To move files around the file system I always have:

ln video new/place/video
mythtv->etc [d]elete video
reget metadata

Are you saying
mv video new/place

The reason for asking not just trying is bitter experience with stuffing-up the database videos dissapear et al
