Thats what I was thinking as well. Great if they now have ET for all feeds and have finally fixed the E vs W issues BUT people need to know ! 
If truly a permanent change then I guess forcing Channels to EST from PST would help BUT that is only if all channels have now been aligned that way.
Another update here. Nick over at SD responded to the SD thread stating this is a change that wasn't meant to go live yet and has opened a ticket with their upstream provider
Hopefully they get all their west coast feeds to also have east coast feeds. I'd probably go back to their service.
FWIW, SD has updated their guides to reflect the change. Discovery, TLC, and Animal Planet confirmed affected.
Any ideas when ChannelsDVR guide will reflect the change?
Are these EST feeds everywhere or only on the east coast?
If someone can send me the discover.json from their tuner I can fix this on our side
I’d be happy to help. Where is or how do I create that file?
Looks like it’s for central and eastern, and just these three channels for now.
Here’s what their support guy Nick wrote yesterday in the SD forum...
“We haven't heard back so I switched the guide for Eastern/Central time zone customers to Eastern for DSC, TLC, and APL so the guide is correct in HDHomeRun apps. The app will show the new guide when relaunched. The DVR will pick up the change in the next 2 hours.
For Pacific time zone customers I changed the feed so it should start playing Pacific content once the HDHomeRun resyncs.
Nick”
Easy enough. Done. Email sent with subject "HDHomeRun Guide Issues- DSC,APL,TLC - JSON files"
Thanks. Wait 10 minutes, then open DVR web UI, hold SHIFT on keyboard and click Check For Updates
New build is ready. After update completed, click circle refresh icon under one of your hdhomeruns
Outstanding. Just updated & refreshed guides. I can confirm that DSC, TLC, and APL guide now matches the content. Thank you VERY much for the incredble customer support, especially for something that doesn’t have anything to do with your code!
Silicon Dust has switched back to the Pacific feeds again for these channels.
Ugh. That sucks. I assumed that was permanent since they said it was their goal to get them to Eastern.
tmm1, can you undo your hotfix code?
Sounds like it was supposed to be permanent, but their upstream fucked it up again.
New DVR build will be ready in 10 minutes.
Thanks. Man they really need to get all of those channels that are pacific to the eastern feeds. It is killing the service.
Seriously, it's a SNAFU back the other direction now? Lovely.
I love love love love ChannelsDVR and have nothing but praise for you guys. But I'm growing a bit weary of SD dropping the ball on various things with HDP. Yet another example of where I question their ability to implement correctly.
Thank you tmm1. Hopefully they get their crap together and you don't have to keep flip-flopping your code.
Hopefully once SD manages to get their own encoders in place (stage 2 as they're calling it), things will be much more stable. But we'll just have to wait and see.
The new DVR build is ready now.
Confirmed. Looks good. Thanks tmm1. I seriously appreciate it. I owe you guys pizza or something 
Absolutely incredible support, thanks for pushing out these corrections so quickly. Great work!
