It's NOT pixelated OR stretched on my local Charge! channel. Has a good pq also. You must have one where the station doesn't know what they are doing. Probably have the wrong Aspect Ratio set for transmission, and as for pixelating, you just might not have a good enough signal level.
The show nowadays are crap too, we can't get high quality shows over the air like Games of Thrones while Canadian get just fine over the air on CTV-2.
We are hand tie by the dumb FCC's censorship crap and hurting the free to air over the air to compete against like ads pay supported channels like FX, AMC and others.
Get sick of seeing NYPD BLUE gets bleeped out and blurred out the nudity part on a good Network H&I.
As for CHiPS is is so lame and cheesy and not worth watching, unless you are being nostalgic since when used to be a kid back in the late 70's or the early 80's.
