After two days of testing (mostly due to the slow speeds), I would like to offer my report on findings.
Motherboard: Asus P5Q3; CPU: Intel Core2 Duo E8500@3.16GHz;
RAM: Kingston DDR3 1333 6 Gig; Video: MSI Nvidia GeForce GTX295
OS: Windows 7 Home Premium
All drivers are current.

I tested two movies, both BD (sorry, I'm not interested in DVDs anymore. Besides, I think DVDFab 6 have reach a perfection in DVD processing, and there's not much to improve). One tested movie is from older release: Independence Day, and another - from recent release : Push.
Coincidentally, this test happened at the same time when I upgraded my videocard (from GTX250 to GTX295).
First of all CUDA issue:
Despite the fact that GTX295 is waaaay more powerful, and considered as "top of the line", I haven't notice much of a improvement in processing speed:
DVDFab 6, BluRay to BluRay mode, GTX250 card - processing time 3:06:17
DVDFab 6, BluRay to BluRay mode, GTX295 card - processing time 2:53:24
DVDFab 7, BluRay to BluRay mode, GTX250 card - processing time 3:23:06
DVDFab 7, BluRay to BluRay mode, GTX295 card - processing time 2:58:14
Pretty much same picture with Independence Day. It appears that DVDFab 7 doesn't employed all resources of available GPU(s). According to manufacturer's description, GTX295 have "multiple GPU". I don't know what that means, but looks like not all of "multiple GPU" are engaged. Maybe this is similar situation, when first multicore CPUs were came out, not all software was able to "see" them and engage into process. I think this issue worth to look into by developers.
Secong - BluRay to BluRay mode (Sttings for Writable Media (DVD-9) Size is 8103 (DVD-R DL):
Output file (folder) size is too big for writing on DVD DL. Independence Day end up being 8.02 Gig, and both ImgBurn and DVDFab VSO burning engines refused to write it on my Verbatim DVD+DL ( 128 Mb too big ).
I end up using DVDFab 6 without any problems - output size was 7.68 Gig.
Also, despite the setting to automatically remove HD audio, I have to check this box again on main UI window.
Third - BluRay to Mobile. This is long waiting feature for me, because I backing up all my movies using BDtoBD option, but actually watching them off the WD TV player/external HDD. MKV container is my favorite. The only flaw I could see right away was resolution settings. With source resolution 1920:1080 DVDFab (with autocrop setting) offers 1920:816 as first preference. Sure enough, after encoding - stretched picture and wide smiles on character's faces I think source resolution should be a default for output, and anybody could change it when needed. Same thing happening in both MKV.h264 and MKV.remux options.
So far, these are all bad news I have. Thank you for your great work - you are in right direction.
Oh, by the way, what's up with the DVDFab.com Logo on output video in BluRay to Mobile mode. I understand it's trial and all that, but it make video useless, and all encodings only for test purposes.
