TV Cards and TV forum. There are a few discussions about that issue, and some solutions.
Also note that MC20 has issues with collecting EPG data, so upgrade to MC21 before you do too much work setting MC20 up . . . Actually,

You will always get more TV related answers posting in the TV Cards and TV forum.
