I have similar issue on one MD, from the Snapshot#23165, I have audio from mp3, Mpeg, wav files but no audio from a ripped DVD I'm using S/PDIF optical connection.

Edit:
The sound came back on its own, I didn't change anything !!!

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???

mathieu,
On the lower left side of webAdmin, click "Show devices tree" then in the same spot click on "My scenario" you get different view, here where I found the duplication

Mathieu,
I'm using #23165 snapshot, I have 4 MDs, 2 of them were OK and 2 did not have the "Media Scenario" even deleting the MD and recreating them today did not work, so I looked into the "My Scenarios" from WebAdmin and found 2 rooms had duplicates so I went to the 2 MDs  that didn't have "Media Scenario" and changed them to a new room and reload/Regenrate All, then I've got all MDs with all Scenarios.

From my experience you can not add squeezbox to a room that already has core/MD, you need to select a room that is not in use example "Garage" then you can go to the floorplan and place the squeezebox Icon.

Alex,
I had the same issue, after 3rd trial I was able to install the snapshot, I mentioned this few weeks back, not sure exactly why

After doing more tests, I found out that playing and transfering Audio and DVD between Mds/Core or playing them at the same time there is no issues.
BUT if you transfer "WMV or MPEG" videos between MDs/Core then it fails you get no audio and black screen.

This issue, transfering "WMV.MEPG" was working in the past

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

Ticket was submitted http://svn.linuxmce.org/trac.cgi/ticket/782

Sure Thom I'll do it in the morning.
Did you see the other UI issue too??

I just found out, when installing a zwave motion sensor "ZIR000" in snapshot #23165, using Sarah, two "Generic Sensors" get created one under (Zwave=>Zwave embedded security interf) which is OK, and a second one under (Core) which is not OK, and causing after reload to get "Orbiter cannot register with the router. Please try again later", I attached a snapshot that depict what I just mentioned.

Solution:
Delete the sensor under the Core and regenerate the oribiter and reload the router, everything is ok at this point.

P.S> I installed this zWave setup many times in the past no issues found, this is the first time I see this.

FYI, when installing zwave sensor and selecting sensor type, Sarah ask you if want to change the name "Generic Sensor" and hit "Next"==> in this screen there is no "Next Button", in order to continue you need to select "Done Button"
I'm using snapshot #23165

P.S. I noticed this in 710 and 810, did not have a chance to record it & I'm not sure if someone else recoded this either.

It happened to me yesterday, I tried almost everything (Regenerating, rebuilding..), the only thing that worked for me is to delete the MD from the WebAdmin, and start from scratch, and it worked the second time.
FYI I'm using "snapshot#23165" , the first 3 MDs I created didn't have a problem.

Can someone confirm the operation of transfering videos between Mds & core using Floorplan on the #23165 snapshot??

Thanks.

I'm not able to transfer a video that is playing on the core to the MD using the floorplan in either direction I get a black screen, anybody has this experience in the "Snapshot #23165" ?
