I had the same problem when using boiled S/N to detect recombinant 
baculovirus. ( I have a hunch that boiling tended to trap the DNA in 
protein which pelleted when centrifuged after boiling) I now use the method 
detailed in Biotechniques Vol 11 pp 177-178 (1991). I have performed this 
extraction method and used it in parallel with boiled S/N. This method 
works reliably (for me) while boiling doesn't.

Admittedly I use virus in S/N but I'm sure this would work with tissue
