"From Hell" compressibility

Apparently there is only one version of this film on DVD; anamorphic widescreen. Smartripper INFO shows it as 16:9 720x480. The best number I have been able to come up with for a compressibility test with DivX 3.11 or 5.0 is .195, which still leaves it off the scale of GK's big resolution slider. This movie is very dark, with hardly any sunlit scenes. Could this be the reason for the low compressibility figure? I've tried a 3-CD spread, but it comes up the same. Any suggestions appreciated. TIA.

This is one of the special-case DVDs where even on one CD it'll look DVD quality. I suggest you aim for one CD size; you'll never be able to tell it apart from a 3CD encode, even if you succeed in making one.

I encoded From Hell a while ago and was able to fit it on 1 CD with Vorbis audio in the OGM format. It compress well because of all the dark scenes. Don't try to put it on more than 1 CD. It will look just fine.

Vampires (r2) appears to be another of these special-case movies, extremely compressible. I could not for the life of me make that one fill an entire cd, had to mux in the director's commentary too, and it was still too small :)

I think I have it right now. 

Thanks to all for the replies. Looks like leevi had it right; my thinking on the compressibility figure was backwards. A newbie's mistake.

Gknot may look a bit confusing at first, but after few encodes you got the idea. Mistakes happen to all of us.
