What i notice on the 404s
head request 404s but get request gives status 200
I am making a good faith attempt to improve in-browser player experience. I can't make any promises as some of the upstream streams are HEVC and thus just becomes a codec issue that your browser simply might not support. I'll push that out next version.
I completed scanning Distro and other sources. The Distro channels appear in new Collections but they still show up as "no longer exists" in the original Collection. I don't see a way to refresh Collections similar to the way we reload M3Us. Is there a way that I'm overlooking?
collections inside CDVR? it should be instant.. what's your settings for that Channel Collection look like?
I don't see anything to set. What settings are there for collections?
I tried cloning the collection and the channels were missing there, too. The channels DO show up on a brand new collection.
One of the missing channels in the original collection is distro.83817. Could that number have changed when I reloaded the feed from Fastchannels and then reloaded the m3u on the CDVR source?
I'm okay with editing new collections if that's what's necessary. I just wanted to avoid it because I did a few edits on the existing collections.
Yes.
It probably changed to distro.US:83817
And when the channel-id for a source channel changes, Channels DVR will also assign it a new channel number if your source is set to ignore channel numbers to allow Channels DVR to assign them.

By fishing around, I think I see what's happening. The previously missing channels have reappeared with new index or ID labels, numbers or whatever the nomenclature is under the hood so to speak. I simply need to remove the channels that call themselves missing. Is close to being correct?
Yes.
Wish there was an easy way to mass delete those.
I find it easier to delete the collection and rebuild it.
yea sorry - side effect of adding region support.
FYI - Distro is a hot mess right now. They’ve changed something and I’m chasing it all day. So some of their streams are up and down. I’ll figure it out.
Thanks! FWIW, Kaloopy's still up.

Of course that's my favorite channel for ummmm... testing.......
I got this figured out. Distro has a few different CDN's for their streams and some require special handling. I'll get update out tonight.
Don't forget region "QQ" is of interest
FastChannels v3.0 — What's New
-
Distro TV fix — Most Distro channels were silently failing on IPTV clients because the CDN requires special headers that clients don't send. FastChannels now proxies the stream manifest server-side and rewrites it so your client connects directly — no video traffic goes through FastChannels, just the handshake.
-
Distro multi-region — Distro TV now pulls channels from all available regions (US, Worldwide, etc.) instead of just one. More channels, configurable per your preference.
-
Sticky channel numbers for feeds — If you have a custom feed with a channel number range, disabling a channel no longer reshuffles all the numbers above it. Each channel keeps its assigned number permanently; new channels fill the gaps.
-
Delete Inactive button — Each source in admin now has a "Delete Inactive" link that cleans out channels that have been gone for 7+ days in one click, instead of having to manage them manually.
-
Smarter stream health detection — Stream audit was incorrectly flagging some live FAST channels as dead (VOD). The check now requires two markers to confirm a stream is truly finished, reducing false positives.
-
Open in VLC — Channel preview now has an "Open in VLC" button for quick testing outside the browser.
-
More improvements to built in stream preview. Almost all channels should play in there (short of a few HEVC/4K streams due to browser limitations)
@KineticMan Just got the new release..
Checked out most of the in-app player...
Could you look in STIRR?
It's the only one that pretty much will not play anything in-app...
All are coming back with the dreaded
Browser preview unavailable for this source (CORS restriction on stream CDN). Use "Open Externally" to play outside the browser preview.
I've tried channels from all the other groups and with a few exceptions, they all played using the in-app.
Note: the 4K channels I asked about all play in-app, with the exception of the one from the STIRR source.
With this said, is there any way to add a stat for nerd setting, or maybe just a show current channel resolution? This way we know if we're getting 4k, 1080p, 720p or worse?
Thanks for the update...
@KineticMan Follow-up to resolution...
How does the search work on this?
I'm on the Channels, tab, "All Sources" is selected.. and the only other thing is, for example, HD (>= 720p), but when I click Apply, the list is empty...
In fact not of the selection works, except for the All...
Is this a feature not yet implemented?
Thanks for the new version!
I'm in need of a channel filter.
Right now for DUPLICATES we have Normal list and Duplicates only.
Since there are so many duplicates it would be nice to have Not duplicate.
Would have made it easy figuring out what the new unique (non duplicate) channels are in Distro QQ
you found it already huh 
run stream audit on your sources then come back and look- it'll populate.
sounds easy enough - just add to that filter like "unique only" ?
