It is ogginfo that reported that a serialno of 0 could be a problem. 
Since they still played poorly after we changed the serial number, I 
don't think it matters to the Cowon decoder.

On these songs where track 1 had a serial number of 0, I tried the 
vorbiscomment example, but they still play choppy on the Cowon G3. 
Since there are only a handful with this particular problem, I will 
reencode them.
