Happens everywhere on most SD channels. Must have something to do with compression and AD conversion. HD channels do not seem to suffer this as much. Kind of looks like when you compress a photo to jpg. which causes blurry edges on sharp objects like text.

Make sure the sharpness is set to the middle in case the picture is too sharp and is exaggerating the ringing. Is the ringing visible from your normal viewing distance?

This is exactly what I get on all channel.
I started a thread about that a while ago. I'd see it on some on Rogers, usually when SD content was shown on a HD channel. I'd often see it on CITY TV news remote video.

I'm quite sure those are compression artifacts. If you take a look at anything
that has been converted from PAL like Coronation Street you will see these
artifacts at their worse. You have the PAL-NTSC conversion and add the
broadcast compression for a truly garbage picture.

As stated above, this situation can be exacerbated by too high a sharpness setting, or edge enhancements turned on, or the wrong (too high) a picture mode - like Vivid/Dynamic. Proper optimization of the TV and STB settings can minimize, but not eliminate these sorts of artifacts. Here's the TV optimization FAQ.

It seems much better with HDMI input, little better with RCA input(tested on the same TV). But too bad, I have only one box with HDMI output.

Thanks so much for everyone's reply, at least I know is not my own or signal problem =P
