Here is the USA, it's more common for cable systems to use us-cable-hrc 
(ntsc-hrc) than us-cable (ntsc-cable). In looking at the actual frequencies 
involved (the xawtv docs include listings), ntsc-cable-ca is a lot closer 
to ntsc-hrc than it is to ntsc-cable (though it's far from identical). I 
don't know what you are seeing that you call "noticeably noisier",  but I 
wonder if you are trying to tune the hrc range using the Canada settings 
and getting near-misses. If so, you might try ntsc-hrc. The same suggestion 
*may* apply to the original poster in this thread, depending on which US 
setting he's been trying.
