I may need a little more info
could be a stereo mono thing ??
I'll make an ASSUMPTION and jump to a specific idea
one should never assume
you are on a Mac ... you have recorded B-WAV files.
I have found that many programs are not happy with the Pro Tools method of tagging a WAV file.
why does PT use a PT icon on a Mono file when PT doesn't play the file when you accidentaly double click on it .... mmmm ?
damed digidesign ... it never used to be like that back at PT4 and 4.3
Use Quicktime Pro to open the file then save as or export the file as a new wav with a new name
now you have a Quicktime WAV and things like Toast and FCP and others ... I-Tunes seems to be happier with the files
frustrating isin't it ?
On the PC Win Media Player also doesn't like a PT WAV file so try a similar save / export trick.
that's all I got for now.
