On Movies and TV shows that I’ve ripped from DVDs and transcoded, on the Roku app once fast forwarded / re-wound the picture seems to then display in 4:3 rather than the 1.78/16:9 or 1.85 it should be.
I’ve not had this happen on Blu Ray media so I suspect the resolution plays a part. It seems to be consistent over the aspect ratios mentioned above when the resolution is 576p or less.
If I go back and watch from beginning, the normal aspect ratio returns until another fast forward / rewind.
A short video clip of it happening can be seen at https://photos.app.goo.gl/yir9jYQy8mTuDfFm6
