Apparently Movies! isn't available in Oregon.
Do subchannels ever broadcast in 16:9? All the local subchannels I have via Comcast (OPB PLUS, which is a subchannel of the Oregon PBS station, as well as Antenna TV, MeTV, and THiS TV) are 4:3, so when they broadcast anything in letterbox, I end up with windowbox (black bars on all four sides), and zooming in reveals just how much detail is lacking.
I have two HD subchannels in my area. ABC is on channel 24-2 in 720p. Fox is on 24-1 in 720p. The CW is on channel 13-2 in 720p. CBS is on 13-1 in 1080i. The picture quality on both channels is amazing. I watched a movie in HD on The CW over the weekend.
