Terrible quality xfinity stream

I am also having terrible stream quality. I can stream thru the iphone app and the quality is 10X better than the tv.xfinity.com stream. I have tried in both Chrome and FF. Neither solve the issue. I have tried streaming on multiple different PCs and the quality of the website is always terrible. iphone sitting in front of me watching the same Sunday night football stream looks excellent. desktop streaming is one of the main reason I pay for this level of comcast service.

Glad I stumbled across this thread because I thought I was losing my mind...same thing, couple weeks ago noticed streaming from laptop the quality was terrible...so tried office computer, same thing then tried messing with settings still no good, thought it was just me or my account, nope it is Xfinity. So Xfinity here ya go, yet another customer with the same problem [Edited: "Language"]/unwatchable stream from a computer please fix it. The TVGO tip was spot on stream quality is excellent.

I just made a post about this same issue.  Then I looked here and see that it seems MANY people are experiencing this.  I hope there is a solution soon.  It's ridiculous to have the quality so poor with 100mb connection speeds etc

Hi, @user_2c9408 and any others seeking assistance on this thread. Currently there is a known issue regarding the quality on the Xfinity Stream website. Our team is working to resolve this as quickly as possible. We appreciate your paitence during this process.

At this time, the temporary solution is to use our Stream TV app on phones or tablets until this issue is resolved. We will update all of you when there is more information or further solutions.  

Same issue, low quality on xfinity stream website using browser... been this way for weeks... Southwest suburbs of Chicago.  This should have been correctly by now.

I'm having the same issue.  When I would select a channel, the video quality would initially be poor and after a few seconds the resolution would change to a good looking image.  Very acceptable behavior.  In the last three weeks or so, the video quality is always poor.  Never improves.  I have seen a number of posts on this subject and all of the normal quick fixes are not working.  I too have tried the normal resets, cache, different computers and the signal quality is still poor.  Please address this issue and please credit our accounts with an acceptable $$ refund.  

Yes same here. Trying to watch live sports but it is like 480p

I watched the baseball playoff game last night on the browser.  TBS gives you a free hour.  The resolution was perfect.  I'm having a hard time understanding how streaming television provided by Xfinity that is providing the Internet can be worse than a third party streaming.  It really doesn't make any sense.

Comcast screwed up their web browser somehow.  I did watch the NBA on TNT last night and it looked fine.  Today, ESPN looks like standard definition where I can watch the same feed from a 3rd party streaming it and it looks HD.

I've had the same issue for awhile.  I did a side by side comparison because I wanted to watch something on ESPN.  While testing on the desktop, the Xfinity.com stream was poor while the ESPN.com stream was high quality.  I was able to replicate this on my Macbook.  I also tested the Xfinity app on mobile and that was high quality.

I'm assuming there's an issue with the browser player and not something on the backend.  The logical thing for them to do would be check for recent changes to the player and find a resolution from there.  Perhaps someone changed the code for the video player to always be low.  Maybe there's an issue with the video encoding but that would mean the mobile and desktop streams are encrypted through different channels.  There could be other reasons but it's not our issue to solve.  It's highly unlikely to be a user related issue as it's reproduceable across multiple devices.

Unfortunately that means there's nothing the user can do to fix this issue besides access the channel through different platforms on the desktop if available.  Low level tech support wont be able to help but hopefully they've escalated it to the right people.

I have tried multiple web browsers on my computer, the quality is still terrible.

Just wanted to add that I am having the same issues. Maybe they’ll take notice if enough of us post on here. I sure don’t wanna waste my time going around and around with customeron the phone.

I am located in Atlanta and am having the same issues. Xfinity stream used to be excellent 720p HD on my browser, but has been horrible as of late. Very frustrating, especially when trying to watch sports. What is being done to fix this?
