Yes I was using the NTSC-M. I am in Oregon and recieve my cable service
from Wave Broadband (aka wbcable.com). I have tried using Mythtv and got
the same results. I haven't tried just trying over the air, but that may be
worth trying even though we don't have the best over the air signal. Of
course, as I got good reception using Windows and Cable I don't expect an
improvment changing to Linux and over the air.
