hi -- This is my first post to the list. I've been helping myself to the cvs source code for a few months now and this is a subject I have done some experimentation with. the only drawback I've found when using --nspsytune in vbr mode is that the average bitrate may increase somewhat

I had the same problem of MMX giving different results than the non-mmx. Maybe the algorithms are different? Is that correct? Isn't MMX (assembly in general) going to use a different algorithm, because if you are using the same algorithm for assembly as you do in C, shouldn't the C compiler give
