Problem playing liveTV using MythTV

[ccoudsi]

MythTV is not playing LiveTV, the reason I believe is the way I have setup my storage, I have 2 HD on the Core and a NAS, I blocked first HD and the NAS from automatic access by LinuxMCE, I want only the second drive to be use by LinuxMCE, so now mythTV is not playing Live TV because I believe is trying to access the first drive, can someone show me how to setup MythTV to use the second drive only (sdb1), I looked at this post but I could not find anything on how to set up the storage by MythWeb per Merkur2k reply http://forum.linuxmce.org/index.php?topic=8498.msg66816#msg66816
I attached my Mythweb storage setup.

P.S. I'm using Snapshot #23165
Thanks

Confirmed the problem, MythTV was trying to access the NAS storage because it has the largest free space, which I had it set as (Read only),
I tried to use "Storage group" from Backend setup, no luck
I tried to edit "/usr/pluto/bin/mythtv_setup.pl", no luck
I couldn't find a way in MythWeb.

Does anyone know how to force MythTV to use specific hard drive for Live TV and Storage???
