Hi,
I found this a bit frustrating myself.
I made the files appear in the select list by adding their extensions into the "host settings" / other settings section, as this was suggested in other posts.
But the trick is the module only supports a few types..so you have to add these extensions and then use files of that type only.
>Valid File Types Include: jpg,jpeg,jpe,gif,bmp,png,swf,AVI,MPEG,MP3,ASF,ASX,WMA,WMV,WAV,MIDI,QT,MOV,RM,RAM,RPM
I was trying to load a mpg, a simple rename to mpeg did the trick :-)
