hi,
i want use the nerocmd for burn a dvd video with my program
i using this code but this only creat a video_ts and not the audio_ts and my dvd player dont recognize the dvd as a movie-dvd and it dont´t play.
the pc can play the movie but the dvd player don´t.
code:

cmd = " --drivename " & CDDRIVE
cmd = cmd & " --write "
cmd = cmd & " --real "
cmd = cmd & " --dvd "
cmd = cmd & " --iso DVD "
cmd = cmd & " --detect_non_empty_disc "
cmd = cmd & " --create_udf_fs " ’ if the disc has data, offer to overwrite or erase
cmd = cmd & " --dvdvideo_realloc "
cmd = cmd & " --recursive " & NEROFOLDER & “*.*”

nerofolder is where the files of dvd are
the format of the dvd is UDF the same as the other dvd movies than the dvd player can play.
