I wouldn't be so sure of the "recommended" intervals of 1.  A quick check
using the media1.pov demo file can show there is a difference between using 1
and 4 (one more than the number of media interacting light sources) and a lower
sample setting can be used without compromising the quality I think.
  I could get a 5 times faster render using method 3 intervals 4 samples 5,5
than I could with media set to method 3 intervals 1 and samples 15,15.  Using
method 2 is even faster still but loses quality, unless the samples are doubled
and then it is actually slower.  It should be said that method 2 can't seem to
tolerate a difference in the minimum and maximum samples without getting a
method 1 look to it, which isn't all bad if you wanted speed and dust graininess
also.

| Actually, it is recommended to keep intervals set to 1 when using
