I’m not personally aware of playback problems that I can ascribe to requiredBandwidths=2147483647. Perhaps this is only a cosmetic issue. But I also don’t have any bandwidth limits configured.
I assume @FordGuy61 will speak up, and there was some other chatter over here:
I don’t think it’s a media curation issue, do you? Poster/cover art attachments are common and legitimate.
In the time Before Plex, I regularly attached poster/cover art to MP4s. I don’t typically do so any more, preferring Plex’s art.
