My personal movie collection is in cloud storage that is mounted to my local home server. When Channels does library scans of my movies it seems like it is actually downloading large portions of the Movie instead of just picking up on folder / file name which is structured per the usual recommendations. I am personally okay with not getting the extra metadata such as resolution and encoding tags that show up. I'm fine with the basic images, descriptions, etc.. that get pulled.
As such I can't really use Channels for personal media, which really bums me out because I love it. I've tried Jellyfin/Emby for live tv and media management and they are simply not as polished as Channels IMO. If I add a movie it will saturate my home internet for 20 minutes to an hour @ 30-50 MB/s while it does library scans.
When I try other media management software like Plex, Emby, Jellyfin they do not generate the same type of network traffic when doing network scans yet yield great results as far as metadata scraped for a given movie.
