I just bought some SCI-fi movies online, and the disk format it PAL section 2. I can play them in VLC just fine, but i want to convert them to NTSC so I can use my dvd player /TV.

How can I convert these PAL DVDs to NTSC images?

the files are separated into numerous VOB files. I was going to try to use ffmpeg, but i do not know how to convert files that are all broken up like this.

You want to convert each .vob into a NTSC? –  Amith KK Feb 19 '14 at 16:23
maybe? I am not opposed to output of a single NTSC encoded file. as long as I can play it in a dvd player. –  j0h Feb 19 '14 at 16:47
Try installing mencoder by sudo apt-get install mencoder Then run this on one of those .vobs to see if it plays mencoder in.vob -vf scale=720:480,harddup -ovc lavc -oac copy -of mpeg -lavcopts vcodec=mpeg2video:vrc_buf_size=1835:vrc_maxrate=98 00:vbitrate=5000:keyint=15:vstrict=0:aspect=16/9 -mpegopts format=dvd:tsaf:tele_src=25:tele_dest=30000/1001 -o output.mpg –  Amith KK Feb 19 '14 at 17:23
