Just wondering what parts of the movie are found in the subpictures. When i am doing a Re-Author to get movie only can i delete all of the subpictures to make extra space without loosing any of the original movie??? thanks for your help

The sub picture contains subtitles, you need to take care in removing all subtitles as often foreign dialog is subtitled as part of the movie. For example the Russian dialog in [the English language version of] The Sum of all Fear will be lost if you remove all the English subtitles from that movie. You could remove all the non-English subtitles though.

Generally though the sub-picture takes up so little space on the DVD that it will make no noticable difference to the quality of the shrunk version.
