I have a tech question. I muxed a few of the 720p SUP files (e.g. English, English SDH) into the 720p despecialized editions. When I play the resulting MKVs on my PC, the subtitles look like they are the correct size in relation to the image.
However, when I play the same MKVs on my Oppo UDP-203, the subtitles appear quite a bit smaller. I tried changing the Oppo from its usual 2160p output to 720p and 1080p, and the results were the same.
Has anyone else encountered this? Is this a quirk of the Oppo? If I want proper size subtitles on the Oppo, maybe I need to mux in the 1080p SUP files instead?
