I have a tablet that I'm running an MC client on to a server PC that has a TV tuner.
Sometimes, but not always (and I don't know what to do to reproduce it), I get an error dialog on the client exiting the Tools/Options dialog (in Standard View), along the lines of "Unable to write timeshifting buffer to C:".
MC on this client is running under the Guest account, therefore should definitely not have access to C:. But I don't know why the client should be attempting to write a file locally when this should happen on the server.
The timeshifting location in the TV options on the client is as the default, i.e. the Videos directory in the user profile (Guest). The location on the server is also as default, i.e. the Videos folder of the user that the server instance is running under.
I assume that, when connected to a library server, none of the TV options on the client are actually relevant or used? Just that the TV feature must be enabled on the client before you can access the TV on the server?
