I'm quite new in DVD authoring world, but I'm looking for a program that allows GPRM and SPRM control... and one that is not sonic scenarist pro as it is quite a bit expensive.
And after that I will have to find a way to program a random selection of files like that (each pool contains approx 20 videos):
play one file from pool1
play one file from pool2
play one file from pool3
and then back to pool1...
