If by “quality” you mean 1080p, then yes, I suppose they are pretty much the same in my book.
x264 release that is downloaded says
Series.Title.S01E01.1080p.WEB.h264-GroupGeneric,
when the x265 release that I would like to be preferred/updated to, says
Series.Title.S01E01 (1080p AMZN WEB-DL x265 HEVC 10 bit AAC 5.1 Group1).
In my profile groups in the 1080p WEB group the WEB-DL is first, and the WEBRip is second. Not sure how just the “WEB” fits into that, though. Maybe that’s part of the problem? WEB is > that WEB-DL?
Oh, I just noticed the Quality column in the results, and in says exactly WEBDL-1080p for both releases.
When I use the priority sorting (exclamation point column), the generic release goes first, and the desired release goes second, both do not have the exclamation point in their rows. So there is indeed something that makes the generic release more preferred. Can something other than quality outweight global preferred words which give +20?
Tried this for other episode, this time it had 2 different WEBDL-1080p releases with x264, and both go strictly above the x265 releases. Then one x264 WEBRip-1080p goes below the x265 releases.
