Thank you for reaching out.
Please go to Advanced Setting > 3D ADJUST > Full SBS Matching and turn on the button when you open a Full SBS video.
This should help correcting the aspect ratio of Full SBS videos.
Also please noticed that this setting will be memorised for individual movie. That is to say, next time you reopen a Full SBS movie which you set the "Full SBS Matching" before, the video should automatically display as the right aspect ratio.
Regarding the recognition on filename, sorry SKYBOX does not support it now.
But we are putting it into our feature request list and will discuss how we could develop such function.
