I don't think you can use the same source. Even though you claim to get the same 
channels as DVB-T and DVB-S, I bet that there are channels avialable with one 
that you don't get with the other, and vice versa (even if you don't want them).

Also, It is entirely likely that the channel numbering is different between the 
two reception methods.

Remember, the information in the *source* tables is what myth uses to tune the 
capture cards, so you'll need different information for each transmission method 
(frequency, modulation, etc.). There may be no reason why you couldn't use the 
same xmltv data, though, assuming you can *guarantee* that the same programming 
occurs both routes. You'll have to either copy the .xmltv file and rename it or 
make a link.
