Why can't I get agarose embedded HMW DNA to digest ?

In my experience, which is now fairly extensive, some enzymes just won't
cut in solidified agarose. Most of these (all in my experience) will cut,
however, if you melt the agarose first, cool to 37C, and then add enzyme.
Also, minimization of the [agarose] will help facilitate digestion.
