Well at least you now know it is making a bad recording, probably. To  
be absolutely positive you should try and play a known good file.

Is this happening on every channel? If it's only happening on a  
couple channels, particularly 4 and/or 5, you probably have the  
frequency table set incorrectly (ie" cable instead of HRC or vice  

If it's happening on every channel check your audio encoding  
parameters, but you may have a defective card, any chance of trying  
another one?
