I created a directory on it called Nasmedia.  It has read, write and
execute privileges set for everyone.  Confirmed though the nas interface.
The nfs is setup on the nas with read/write permission for everyone and
no_root_squash
I can read or write to that directory under any user from any computer on
my network.

On the backend running mythbackend i have fstab set like this.

192.168.1.222:/Nasmedia         /home/mythtv/qnap/      nfs defaults 0 0

I do not know a great way to show folder permissions so I have done my best
and pasted below

User mythtv, or anyone for that matter can create directories or files
anywhere along that path

If i setup the storage groups to use /home/mythtv/qnap/mythtv/storage, live
tv will fail
If i setup the storage groups to use /home/mythtv/qnap/mythtv/livetv, live
tv will fail
If I setup the storage group to use /home/mythtv/livetv, live tv works.
I can set the storage group to anything on the local drive and live tv
works as long as I set the permissions correctly on the chosen folder.

I can record programs while the storage is set to nas.  And playback works
fine with the recorded programs.
Its just live tv that fails.  It starts for about 2 seconds, then stops.


I am okay with leaving it like this.  I am just trying to understand why
its failing live tv.
