Greg,

That's because in IDV2.0 there was a bug in the version of nj22 that 
skipped duplicate records in the grib file. The bug has been fixed.
 For instance, here's 2 records from the grib index file.

1 0 -1 176 8 103 8229.0 255 0.0 2006-12-18T23:00:00Z 0 921322765 2164150 
2206536 2 false

1 0 -1 176 8 103 8229.0 255 0.0 2006-12-18T23:00:00Z 0 921322765 3394504 
3405226 2 false

fields 2-5 determine the parameter, so the parameters are the same. it 
also has the same level 103 8229.0  so the 2nd record is a duplicate of the 
first including the time. Thats the first problem. The second problem is 
the number of points from the GDS, Nx = 301 Ny = 225 should have 67725 
points. The first record has 67725 but the second only has 17063 points. 
That caused major problems when you try to display the parameter. You need
to point this out to the data provider. is this file a combination of 2 
different files? the GDS Nx and Ny are wrong for the records that only 
have 17063 points.  Why are there duplicate records in the file for all 
the parameters? Can you send the data provide the file and have them analysis 
the above problems. If the wrong duplicated were eliminated, the file 
could be read/displayed properly in the IDV.
