If you have your HOME (and, therefore $HOME/.mythtv ) directory mounted 
over NFS, or if you have the Images Storage Group directories or the 
MythVideo (local) directories (if you're not using Storage Groups) 
mounted over NFS, make sure you're *not* configuring those mounts the 
way we've recommended you configure your recordings directories ( 
http://www.mythtv.org/docs/mythtv-HOWTO-23.html#ss23.9 ).  You need to 
enable NFS file attribute caching on the Images/MythVideo directories.  
So do /not/ use actimeo=0 or noac and make sure, if you do modify 
actimeo or acregmin, acregmax, acdirmin, or acdirmax that you use 
appropriate values (as can be found through trial/error if you really 
feel you need to adjust them).  NFS defaults should be appropriate, 
though.  You /definitely/ need at least actimeo=1, but higher is 
probably better.

For the recordings directories, actimeo=0 is useful to allow Live TV to 
work properly.  It will kill performance, though, if you use it on 
Images/MythVideo directories.
