[QUOTE=signals;154577]Jagged edges are often caused by improper processing of interlaced content. Check your source files with MediaInfo (free).[/QUOTE]
Thank you for the information. However, when I play the source files (1080p MP4s) with VLC on my 60-inch 1080p TV screen, they do not show the jaggies. It's only after processing the MP4s with DVDFab Blu-ray Creator, and then playing the resulting Blu-ray folder, also with VLC on my 60 inch TV, that I get the jaggies. That's why I think it is something DVDFab is doing, or maybe I need to change the settings for Blu-ray Creator.
Any ideas?
