That might be it. Handbrake automatically crops letterboxing. Redo the conversion in Handbrake, but before you hit start, change the cropping to “custom” and turn all the values to zero.
Tested out a small sample video on custom crop and it works perfectly now, Thanks so much to the both of you. I knew pretty early on there was no subtitle file but had no idea that handbrake auto cropped the video like that.
Thanks again
