The following was observed with both versions using all default options and the PS3 profile
On DVDFab Platinum v 188.8.131.52 a 2 hour movie file size was approx 1 GB and averaged 1.2 Gbits/sec data rate on playback
The same movie on DVDFab Platinum 184.108.40.206 is about 640 MB and averages about 500 k bits/sec on playback.
Overall the picture quality is a good deal poorer at the lower playback data rate. The only thing that did remain constant was the encoding times.
Any suggestions to regain the higher resolution? Again, no options were changed with either version. Even though 220.127.116.11 indicated the data rate was 1.2Gbps, it did not play back that fast.
