I have had problems burning DVD's from my video editing software (Pinnacle) and have posted on another thread here. Other burners work well. Pinnacle will save as DivX, Mpeg-1, MPEG-2, MPEG-4, Real Media, Windows Media, Sony PSP, or AVI (or Ipod). I need to know what program I can use to convert these so that they can then be burned to a DVD for playing on a computer or DVD Player? Is there a program that can do this all (hopefully freewhare)? Pinnacle does not make an iso file and so I am having problems. Also what is the best file to output to a file from Pinnacle from the list above to then use a program to burn a DVD? Any help is much appreciated! Smokey
