Hello Roberto,

I investigated a little and I know now what a MDPR chunk is. You're 
right that dumped filed the file doesn't have a MDPR chunk.  What I find 
strange is that most fields of the PROP chunk are empty. All fields 
except the Number of Data Packets in the File, the Offset of the first 
DATA chunk and the Flag are null. Could be this maybe the cause of the 
problems?

Ciao,

Hernan
