If you post your NFS config questions here, more people can help you.
Re-read the Guide first, and try to follow step-by-step. Though, since you try setting up NFS btw 2 Linux flavors, NFS Client setup will differ, so look through ArchLinux NFS Wiki too. Read
more on choosing a proper file system for your media drive. If your playback keeps jumping, check with Htop no other processes (like Webmin) periodically top load Plug's CPU.
Keep in mind,
udev-automount rules are used when you hook up a drive to Pogo
after boot, while
fstab rules are used
during Pogo boot for all hooked drives, and when manually mounting a file system (FS) after its manual dismount. The rules are comprised of FS specific + common to all FSs mount options, so look at
udev and
fstab files and wiki to understand how rules work.
