i am trying to author a dvd bonus disk with a number of small titles containing special feature commentaries. i ripped and burned with shrink and am importing the files into tmpgenc author from the burned dvd, they are automatically read as mpg with ac3 (if i try to import straight from the hard drive rather than the dvd the files won\'t open because they aren\'t converted.)  this normally works fine, but strangely, these commentary docs seem to have been made in sets of two or something, because every other one that i try to import will not open and i get the error message \"audio existance differs from the present track.\" when i try to open those odd files as a separate project they open, but with no sound.
the burned dvd plays these files just fine. any ideas?

I do have that! And it works on every other file.
