did I miss something / channel autotune - mapping

Hi every one!

I'm currently trying mediaportal, and I'm pretty impressed of the whole thing, it must be said...

The only problem: Channel mapping is quite complicated or difficult to understand....

I live in Quebec, and channel line up is really simple: channel listed in xmltv are mapped on our tvs in the same order.

My question : Am I missing something or am I forced to map the 80 channels manually ?

If there is any way to do automatic mapping between auto-tune and channel listing, can someone light my candle ?

If not, I think that a simple implementation would be the same as european tvs: simply map the channels automatically, in xmltv import order, and than let the user reorder them by swapping channels...

Thank in advance for any help that anyone can give me
