ISO 9660 is the standard for CD’s that has been used for many years defining how CD’s are witten. UDF (Universal Disk Format) came along with DVDs and is being used on other media as well.

  1. I have a wedding video made for my daughters wedding and it will play in a computer dvd (not a cd player) but will not play in a regular dvd player for home use. Can you give me some idea why? It says under properties that it is a UDF file format. Is there any way to convert it so that it will.
    Thanks

  2. Rip the dvd to your computer (the folders/you may need a program for this, google)
    Copy files to another dvd (you may need to encode the movie again (nero does it, cant remember what part of the program)). Enjoy!
