For media, the minimum/maximum mechanism is ONLY for sampling method 1
and 2 where you have multiple intervals.
Now, with method 3 been the default, only the first value is ever used.
Any second value is silently ignored. Also, ratio, variance and
confidence are NOT used anymore as the are used to control how many
samples are taken in each intervals.
The sampling defaults for media are:
method 3
intervals 1 // MUST stay at that value
samples 10 // must be 3 or larger
jitter on
ratio [NOT applicable as there is ONLY a single interval]
variance [NOT applicable as there is ONLY a single interval]
confidence [NOT applicable as there is ONLY a single interval]
Increasing intervals have horrible effect on the rendering speed. I
know, I've done my testings.
