Hi, yes looks like you guys have resolved the glitching in the latest build. I have attached some photos that depict the aspect ratio problem. I can confirm that this only occurs with SD channels. HD channels all playback full screen. You can see that with some channels The image is not even 4:3 aspect, and the image is not scaled correctly. With the standard video player enabled all of these channels playback full screen and look fine. 
Sorry about the photos being upside down.

I’ve noticed a few issues with the experimental video driver enabled while watching live tv. The screen appears to have tearing issues pretty regularly while viewing live tv. It continues to play just fine with the exception of the banding/tearing issue. As soon as I turn the experimental video off, the live station plays fine. Not sure if it matters but I use a cable card with a HDHomerun tuner for Channels DVR.
Things I’ve tried:
- turning off match content (Apple TV)
- turning off match range (Apple TV)
- changing resolution to 4K HDR, 4K SDR
- changing all settings and rebooting Apple TV
- Updated Channels server and full reboot of both PC and Apple TV
Is anyone else experience this issue?
See:
Thanks. I was able to reproduce this on some channels and have some ideas on how it fix it.

Please try 7.4.2029
Hi, just downloaded 7.4.2029, switched to the experimental video driver. Unfortunately SD channels are still presenting the black bars with incorrect aspect ratio. Included another photo for you.
Could you click Support > Submit Diagnostics immediately after playing that channel.
Ok just submitted diagnostics
Does it happen if you make a recording and then play that?
Please try 7.5.153
Hi, this build has fixed the issue. Many thanks.
Sorry, a bit premature with my reply. SD channels are now rendering at full screen using the experimental video driver, however, the image is not stable, it’s tearing and juddering which doesn’t happen using the standard driver. I have just submitted diagnostics after playing back some live OTA content.
Thanks! Please try the latest beta 7.6.150 which should fix the picture issues.

Wonderful! Appreciate your help testing.
Are you noticing any difference in colors on SD channels between the new and old driver?

New build is out (7.6.1919) with improvements to color mapping for standard-def channels. Some rare crashes have also been fixed.
The Experimental driver should be stable enough now to use full time. Please try it out and let me know if there are any issues.
I’ll do a bit more comparative testing on this, but I have to say that my limited usage of the experimental video driver since downloading the latest build has been impressive , across SD/HD. I haven’t watched much 4K HDR content as yet, what I have watched looks really nice. Thanks for your efforts to make a great product even better.

Just wanted to say I played my UHD HDR The Fast and the Furious and had no issues that I could see. Hopefully I’ll get around to watching more, but with no real new movies coming out it’s a slow time.
This Video Driver is now the default setting. The old default has been renamed to Legacy.
