David, The XSize of a dataset should always match the xsize of the bands fetched with GetRasterBand() on the dataset. However, bands for overviews, fetched with GetOverview() on the band will not have the same size as the base band or the dataset they are loosely associated with. In some cases the overviews actually are directly owned by a sort of hidden dataset but that may not always be the case.
