Did you burn it in DVD Video format?
Your computer and some DVD players may be able to play movies in formats, that other DVD players cannot play, such as AVI, MP4, M4V, MOV, XVID, DIVX, or other formats.
I don’t know the specifics of your Durabrand and Sony players, but the only format plabavle by all DVD players is “DVD Video”; this can be recognized as a VIDEO_TS folder containing some *.vob , *.ifo and *.bup files, but the disc also needs to be burned as a “DVD Video” disc (which means UDF 1.02 with a ISO9660 bridge) and not as a plain data disc.
It may be easier to know if the disc is in the right format, if you tell us which program(s) you used to create the disc.
