First, why? you should be receiving all the OTA channels on your QAM line, 
from either a better positioned antenna or directly from the network 
digitally (depending on your cable company).

Out side of that, you can get a splitter/combiner from home 
depot/lowes/radioshack, run the two lines in and the output to the card. 
you'll have to customize the channels information in Myth to understand which 
channels are on QAM and which are on ATSC as well as the multiplex 
Haven't tried it but it should work.
