Can I ask JR to auto import automatically?
I think so yes, if you mean force autoimport to run that is. Never tried honestly, but read this =>
http://wiki.jriver.com/index.php/The_Command_Line there is a core command option /import to run on start-up, so that shoudl do what you want.
Understand that autoimport is a low priority operation (with a lot of terabytes on a slow network, this takes time); setting to a high priority is probably not a good idea.
Frankly I never wait I just click Import manually -- I put a shortcut directly on the main menu bar of MC and click it; otherwise of course its File=>Library=>Import.
The only reasons I can see
not forcing autoimport to run when you want it is for people who are recording TV when they are away (or downloading stuff that maybe they shouldn't be) and they want jriver to tag and analyze everything while they are away. couch potatoes have to compromise speed for the ability to be lazy
For people who rip audio cds, I see no reason. You rip, you click import, you tag when you want to, no big deal.
Analysis and looking up tv/movie info is slow (depending on set-up and hardware - on a network this can be painfully long). I do this later at my convenience by setting up a smartlist to see what still has not been done. Personally the auto tagging from internet is so often wrong you I'd be correcting it anyways - my opinion but hey I want speed so anything
auto other than fixing broken links and external changes being re indexed, including rebuilding thumbnails or such, I do as a separate maintenance routine while I'm watching or listening to something in the background.
Just my opinions here of course
