It sounds like you're creating "shadow" channels (i.e. multiple copies 
of channels, of which one is properly linked to the source/getting 
filled) or something.  This can also happen when you have 
unconnected/partially-configured capture cards or video sources (but if 
it's really happening right after channel scans, it's more likely shadow 
channels).

I highly recommend always deleting all channels in a Video Source before 
rescanning (ideally, just doing "Delete all Video Sources") to make sure 
there's nothing extra in there that you may not notice.
