@ianfontinell I agree for the most part. The simple instruction to include, clearly why "this" .mkv is different to "that" .mp4 + .gb.srt + .sp.srt + fr.srt is reasonable, especially given a mod needs to be able to make that determination fairly quickly, and other things - size, resolution, etc. - might otherwise make it look so.
My "issue" is that I suspect many, as I did, will start from the basis that a .mkv containing softcoded English and Chinese dubs, all in one file, is a different format - and therefore not a duplicate - of a torrent containing a .mp4 + those two .srt subs.
I do, though, feel there should be a clear note in the definition of "duplicate" that an .mkv IS considered a duplicate of a .mp4, UNLESS it contains additional elements not included in the original torrent, and that these differences should be clearly stated.
