Streams defined with Hydrology tools don't always fit in channel

I've been trying to define a stream network from a DEM raster but the streams Spatial Analyst>Hydrology tools defined do not always match with the channel when compared to the Terrain/TIN. For a good majority of the stream network it fits, but not everywhere.[ATTACH=CONFIG]20931[/ATTACH]
I've filled the sinks. My advisor suggested running Focal Statistics multiple times to smooth out the slopes of the stream banks, but no luck.
I've been stuck on this for a while. Help is much appreciated.
