on all DVd players??

P.s I m from mexico

Fist of all, you need to burn this as a "video DVD" and not simply a DVD that contains computer files.

Secondly, you probably need to burn this on DVD-R media. I think it reaches a few more players then DVD+R and certainly more then DVD-RW or DVD+RW.

Lastly, some players (mostly old ones) won't work with any burnable media.

I am assuming you're only interested in players in your own country. US and Mexico use NTSC. I don't think NTSC disks will play in countries that use PAL or SECAM, such as England or Russia and their colonies.
