[mythtv-users] splitting signal?

[Benoit Beauchamp]

i plug the cable coming from the wall directly to the computer and  
started messing up with it. ive figured out that my cable provider  
uses cable-hrc or whatever it is but for some weird reason there are  
few channels that are scrambled?! doesnt look like premium channel  
because i have basic cable, i can watch msnbc but cnn is  
scrambled. . ?!? do i need to mess with frequency or something?
