I have CC/teletext data on my list of things to use in Commercial Detection, but I haven't got around to coding anything on it yet. My master backend currently has three AVerMedia M179 cards and the driver I'm using is kinda old so there's no chance of having CC data there. Once CC/Teletext data is working with the DVB drivers (I have a pair of air2pc cards in use as well) then I'll take a look at using CC data from them to start adding support in the Commercial Detection code. -- Chris
