Actually he said he ws *downloading*, and so he probably doesn't have 
control over the incoming stream.

Remember that you can only really control outgoing rates properly - 
incoming streams you control indirectly and all you can do is ignore the 
sender for a while and hope he stops sending you stuff so quickly... So 
this is probably your problem - HTB reacts instantly, but the sender 
keeps sending stuff for perhaps several seconds until you stop answering 
him and then backs off - there is a reaction lag and there is not much 
you can do about it really.
