When playing MKV made from DVD ISO, video is not letterboxed. I'd rather not go through all my ISOs and make them into MKVs. This doesn't happen with Bluray ISOs. Secondly, when playing DVD ISOs, Dolby Vision VS10 doesn't get activated for some reason even though I have it set to get activated on every SDR and HDR10 video. This also doesn't happen with Bluray ISOs. Thirdly, when playing DVD ISOs, when I press the "Play video" button instead of the "Play with Blu-ray menu" button, it doesn't play the video it plays the whole ISO with all the previews, trailers, menus, everything. And when it gets to the menu screen nothing is selectable. This also doesn't happen with Bluray ISOs. Z10 Pro with 6.3.92 firmware.
