We're getting there, but we must put more intelligence into the plugin, before it is the preferred way for everyone to make SVCDs. (even for the multipass fanatics).

I changed GOPs to SF Range (sample frame range). I am experimenting with using fewer frames than one GOP in the SelectRangeEvery, in order to get a lower "every" number with the same Sample %. That gives a better distribution of the samples (every 17 sec, with 2%), but makes awfull short cuts.

I've tried 4, 5, and 8 frames, and it seems 8 works quite well (instead of 15). You'll need to boost the Adjust Q a bit, but it should give more stable estimations. I have also figured out another way to safely cut down number of tests by 1-2 (from 6).

I'll throw out the version for you to play with when I got time.
