Hmmm.....so I'm trying to make a Blu-Ray from the .mkv using the same method I used to make the awesome v2.5 despecialized but something is messing up the aspect ratio on playback. And, strangely, only my Oppo BDP-83 can play it all. When it does, it is stretching the image vertically (thus eliminating the black bars). Before you ask, no it is not my TV or the BD player, as they play all other discs just fine.

I suspect it is probably tsmuxer. The last time I did anything with it, I was all the way back on version 1.10.6 I believe, but I started with recent versions of everthing this time around and tsmuxer is at 2.6.12 now. I do see some changes to the interface for sure. I have some vague recollection that the older tsmuxer is preferred for this source material, but I could be wrong. I also remember seeing the option to create a "blu-ray folder" (and, in fact, that is what I did before) but that is missing from 1.10.6. In short, I am confused to say the least.

Since I usually just take the default settings for everything, does anyone know what I need to look at to fix this?

Perhaps the AR setting? It is at "As source" right now, which also seems to be what is was with the older tsmuxer. If I change it, none of the other choices seem to be good. Certainly not 16:9 as that is what I think I am getting now.

Another possibility is ImgBurn is doing something but I do not think so. I used the latest version of that to burn an iso from tsmuxer and then an older verion (2.4.2.0) to burn a Blu-Ray Folder. Both gave the same results.

I want to get this right for my next burn. Already wasted two BD-Rs. :(

According the info I read on tehp..., the resolution is 1280x540p... So the source video is not a 16:9 ratio (which is needed for blu-ray discs, if I understand it correctly). It looks as if the black bars have been trimmed off, leaving just the picture for the film itself. However, I've noticed that the AVCHD version has a resolution of 1280x720p, which is 16:9.
