Cannot Map Channels

I am running TVHeadend on a Raspberry PI with OPENElec. I have an Happauge PVR 1950 for a tuner. The device can find the available services but I am having a problem mapping the channels. Funny thing is that if I go into services I can actually tune the channels under services and it plays but I cannot map them or record anything. What do I need to to in order to get the channels mapped.
