SD channels now in windowbox format

Same thing is happening here (outside Chicago) as well.

We tried everything possible on this end. Countless power up-downs, reboots of the router and the X1 box, unhook-rehook, zoom, not zoom, Several resolution changes. Had a tech out here that did all the same himself and agreed it is a back end issue, either at Xfinity or the SD provider to Xfinity. This is certainly an issue on your end as it affects the Xfinity stream app too. You need to reach out to your in-house tech people and have them go back to vertically zooming the SD content. Also yesterday, all day instead of just black borders, the left and right were bright blue as the image I posted shows. Today back to black borders. Please get this resolved as it also isn't great for the longevity of the TVs.

@XfinityThomasA​   This is a Comcast issue not a user issue! We all have been through everything possible on our end with no help! 

@user_1b8f41​ I've been fighting with support about this for almost a solid week, rebooting, powering down and up, unplugging and plugging back in, checking cables, rebooting routers, removing AVR from system. The techs refuse to admit a backend issue on this, Went back over two years on the forum and found the same issue back then, and no fix other than suddenly things went back. Got a DM today that there is a system wide update on the 12th, in the early hours so maybe that will take care of it. Fingers crossed.

@user_1b8f41 I can appreciate how frustrating it is to not have a full-screen image when trying to watch your favorite programs. Have you double-checked that your firmware for your device is fully up-to-date and try uninstalling and re-installing the Stream app to make sure that you have the latest version?

Does it affect the sub channels when you use the Xfinity Stream app too?

I'd love to not have to watch SD either but there are many SD channels that don't have HD equivalents. Like MeTv, H&I, etc. When Xfinity chooses to send properly formatted HD versions of ALL SD channels, this won't be as big an issue. Also had Verizon for years and their boxes had an SD passthrough if you knew how to access it. At least Xfinity could fix the zoom feature to expand BOTH horizontal and vertical aspect not just horizontal. There is NO practical reason for this change.

Same issue in Maryland. Spoke with Xfinity, tried all the reboots with no success!! Xfinity....please address this issue! For $290/month, we deserve viewing in same format as 1 month ago (1.25.25). Please help!! Issue with TCM and MeTV, most obvious.

Happening using the Xfinity app on a brand new insignia 32 Smart fire TV, ME Tv had black bars as LL the way around it and a white line across the top bar .doing the same thing in other room using the cable box. If I use an antennae it is fine , this is a Xfinity issue.

@user_uodi5k​ this account was just set up today, fresh cable box, I also reinstalled the app on the the 32 inch new insignia, no change.

@user_i8r2sd​ I was told finally by Xfinity support to live with it as it WILL NOT go back. So there you are. Thanks a lot Xfinity!

Hi there, @user_i8r2sd! Are you still running into this issue at home?

He might not be but I still am. Absolutely nothing but avoidance on the part of Xfinity. No direct answer, and no hope for a resolution. I was told "give it up because it isn't going to change back" by the last tech person I spoke to. I would have hoped your service was better than that.

@user_xldu7p
