When I put Kodi in 3D Mode and play HSBS & HTAB movies they play fine. When i play SBS/TAB movies, Kodi sees it as tho it is a HSBS/HTAB movie and will stretch the image. This results in a streched video.
I've found that while playing the video I can go to Video Settings -> Pixel Ratio, and set that to 0.5 to stretch the video to its normal aspect ratio. But since I also play very short 3D videos in front of the movie through a playlist, this is not an option. Setting this pixel ratio as default will screw up the aspect ratio of other videos.
Does any one know a solution to this? Would it be possible to tell Kodi to do the pixel ratio setting automatically when .SBS. or .FULLSBS. is found in the filename?

Not if it is actually being frame packed rather than sent to your display as SBS (sending SBS to the display in a 1080p frame will always act like half SBS, frame packing or a 4k display is a must). This should have much the same effect as changing the "Pixel Ratio" in Kodi, it's just picked up automatically.
Editing this header works quickly, even over a LAN share, and there is a box "Remove element" that you can check to revert back to the way it was, so it can be tested safely.

SBS/TAB videos are not MVC (Multiview Video Coding), which are required for full frame 3D on a Pi (MakeMKV can rip them from disc). On a technical level they work so differently as to require different classes of hardware; MVC is possible to decode with hardware that is similar to what is necessary for a 1080p video (just clocked higher to basically hit a higher framerate), while full SBS (3840x1080) / TAB must be decoded with hardware that is similar to that needed for 4k videos (just requires less memory and memory bandwidth, as it only needs to decode 2x the frame size), and the Pis are definitely 1080p devices with extra clock speed.
It can be real finicky to get 3D just right, but is totally worth it; my 6 year old Sony projector has a far better 3D effect than any theater, even according to my movie buff friend, so this is something I've worked to perfect. Tron Legacy is the overwhelming favorite, all the CG and the subject are just perfectly visualized in 3D (you're looking through a window into another world!).
