I am beginning an extended project and I want to use Cineform. Given the following computer and types of footage, what Cineform Product is recommended. (Also, is the the Cineform engine a distinct advantage when using Premiere CS3, and does the Cineform engine also work in AfterEffects?):

Computer:
ASUS P6T deluxe
i7 920, with 6 GB RAM
2 TB space RAID 5 for capture and edit.
Additional storage options in and out of computer
Nvidia chip GTX260
Premeire CS3, AfterEffects CS3

Project edited in 24p.
25p version also needed of final project.
(1080i small projects also edited)

Cameras and codecs used:
Canon HV20 - 24p in 60i
JVC HD110 - 24p, 30p, 60p/576
Canon XHA1 - 24F, 1080i
JVC HM100 - in all progressive formats (XDCAM EX codec wrapped in MP4)
Misc. other standard formats
===============

It would appear that NeoHD would work well, but is the Premiere engine in Prospect a significant advantage if editing with CS3?

Does Prospect have any advantages over NeoHD besides the RT engine given the above requirements?

Effects is not accelerated in the same way, too many filters to replace.

Prospect adds many things over its real-time engine (you need more than that?) It integrates into Premiere's capture engine to support timecoded batch capturing, adds HDSDI support via AJA cards, added many 32-bit float filters which Premiere has so few of, it will even tells you if a filter stack is 32-bit float or truncated to 8-bit. These is more, but that should be enough. No CS3 users should be using NEO HD, Prospect HD is the way to go.

Very good, thank you!
