Thanks, have replaced the file and restarted the service, but when trying to run a grab now, I get 'error occurred - unknown error' after the 'grabber set to grab 60 seconds' message?
edit - now also get unknown error when trying to view live tv - do I need to do anything else?
DJBlu - just redownloaded both tswriter files, and they are the exact same size with the same timestamp - just wanted to check that the 2nd one was not a repost of the first file?
