Hi
I would disable spin up/down of disks anyway.
Is this mainly because you want more noise in the living room, because you want the disks to die sooner, because you want more heat in your VDR PC or because you want it to waste more power? ;-)
You have 9 disks in the living room ? That sounds crazy to me :-) You are right with noise and heat, but the disks will live longer when you disable spindown.
And vdr doesn't know what disks are involved.
I am using only a single /video directory on the system disk. Directly under /video, I have one directory for each genre. Those are symbolic links pointing to other disks, some of which are local disks, others are NFS-mounted. It would not be hard for VDR to follow my links and find out which disks are really involved, but I guess currently there is no such code in VDR.
Surely not, and vdr should not mind what hardware is behind /video. But there is surely a way to put stuff like that into a plugin ...
