I have a setup with a master back-end using storage groups for media storage, and multiple front ends, some dedicated, some just the front end software installed on a desktop or laptop along with an existing desktop.
The problem I'm running into is that one of the front ends is unable to play back video from the master back end. Note that I'm not saying it won't play back recordings. Those work. It's Video that is not working. This is not directly an issue on other systems, which is not to say that other systems are not demonstrating problems, I have to be careful which system I run 'check for updates' on, as some of the systems just wipe the database of video information and say that there's nothing there, even though it's perfectly happy to play the content and show the library if it's built on other systems.
All systems are using release 0.25 of Mythtv.
This looks to me like the front end is configured to look for the videos locally, and is not finding them. However the media setting general settings 1/4 'Directories that hold videos:' entry is blank on each of the front ends, since the videos are stored in a storage group on the back end.
Pretty sure that I'm missing something that should be easy to find as to what's going on with the host that's unable to play video content. I'm not finding anything obvious when doing a google search, though I am getting hits, they are mostly related to content on a slave backend which is not pertinent to this problem as there are no slave backends setup at this time.
If anyone has a recommendation, I'd love to tag this thread as [SOLVED] before the next LTS update comes out. And I'd prefer the solution not be 'upgrade to 0.26' or 'run from the git source', as neither of those are going to happen any time soon. (Not running 12.10, and won't even look at 13.04)
