From my understanding, MSN and 3DNR are separate technologies. MSN is a 2D noise reduction (specifically attempting to find MPEG2 mosquito noise on a frame-by-frame basis), whereas 3DNR, which some call 'random noise reduction', is specifically for noise found during motion. The latter not necessarily and artifact specific to MPEG2.
Granted, some processors/TV's may couple these techs together, but they are separately adjustable on many others. It should also be noted that DVDO does in fact have 3DNR on some of the processors, including the Vp-50pro.
As stated though, in my experience Alogolith's tech is the best available, and that includes what I've seen from Silicon Optix (Reon in my case).
