Just had the exact same error as already described. Tried to start the TV and keep getting the 'Unable to start timeshift, UnknownError'. Difference with the rest is that I have a DVB-C digital tuner. Tried applying the patch given in the thread and that did not resolve the issue.
Sometimes restarting the computer does resolve the issue.
