Looks like the known problem with the NVIDIA video decoder. All the channels you're seeing problems with are 1080i, while the working ones are 720p, which is consistent with the problems we've seen in the past. Can you check CBS tomorrow afternoon and see how it looks? They've got racing and basketball on which would be good tests.

That pretty well confirms it to be a problem with the hardware doing the decoding. Local broadcast stations don't go through the same encoding path as cable channels do, so they aren't affected (except when the station happens to be using the same encoding setting that triggers the bug). Unfortunately since it is a flaw in the decoding hardware there's nothing that can be done about it at the app level.

So, with the new Shield TV out, I'm wondering if anyone with this issue has tried them. Sadly, I just can't find a good alternative to the Shield TV, so I'm likely to buy one of the new ones if it fixes the issue.

Any feedback would be appreciated!

I would like to know this as well I pay 300$ for my shield pro thinking I was gonna be bug free with no issues but I was "wrong" the shield surprisingly is not the best Android box out for the hdhr because if I can't watch my own home town sports teams then is basically useless I think silicondust and Nvidia should stop pointed fingers and get to the bottom of this and fix it

Well, I decided to try purchasing the new device myself, since I couldn't get a definitive answer. Unfortunately, the new device (Shield Pro) still has the same issue, so I'll be returning it. What a shame!

nVidia, get it together!

EDIT: Does anyone have any recommendations for a different streaming box? I need one that can handle local media from my media server via Kodi and pass through HD audio, including Atmos. I also need it to handle proper MPEG2 decoding via Kodi for my local channels. In addition, it needs to support 4K HDR and Atmos via the major streaming services (Netflix, Hulu, Amazon). I suspect there really isn't a box that will do all that well, but thanks in advance for any suggestions!
