Ok some further info....
I just tried changing back to the "main library", scanned the TV channels, quit MC and then started again. TV Channels are still there. If I change to the share library server then all TV Channels are lost.
I think I understand what is happening here, however it's not an optimal solution! I'd consider the TV tuner and channels to be a "local" resource, not something share from the MC server, unless those TV channels are configured on the MC server. Being a local resource they should be available on the client at all times. (Think of the analogy of a local CD/DVD drive - would you expect to lose access to a local CD/DVD drive it you were using a shared library and the server didn't have a CD/DVD drive?)
Is there a way around this?
Is it a bug or feature omission?
How can I use the shared library functions but still be able to use the local TV Tuner and channels?
The TV Channels will be the same across both pc's, so is there a way to save these channels to the server and share them? Would that be a work-around?
thanks!
