jtv
the latest error was a snooker match. Could it be because it has the same name as the second session in the match that played in the evening? Both files are named "Snooker_ Players Championship Live 2016-03-27" but the evening recording gets a (1) appended. Both recordings seem to have the correct files (jta, jtf, jti, jtr, jts, jtv and all the numbered jta and jts cnk files)
I've attached the error I get with the first file (The non (1) file)
