Try acrobat pro extended 9

I can explain a little.. of how this software works.
Mobipocket creator hacks up PDF file in an unintelligent manner. If it is a SIMPLE file, it will get the job done, in an OK manner. If the file is very old and simple and THROWN into a PDF container, it will work, but other versions will also be available, because it was batch converted into PDF as well as RTF, DOC, MOBI, EPUB, etc.

Mobipocket does this.
1) Extract all image files (raw image files dumped to directory)
2) Text reflowed logically from containers into columns to form ONE solid body of text
3) Images are reinserted into body

Acrobat does this (HTML + CSS).
1) Screenshot images (in context) containers near text (may capture text too, charts/graphs/tags/labels)
2) Text reflowed logically from containers into columns to form many paragraphs and blocks of text
3) Tables and layout tagging is generated
4) Images, tables, paragraphs combined into body

Mobipocket will give you PDF -> HTML, but you won't get much formatting.
Acrobat will give you PDF -> HTML, and you will get size, centered text, tabbing, tables, etc.

Acrobat may handle images strangely in older PDFs or batch converted PDFs. If you have a graph with axis labels, it will TRY its best to incorperate them into the image, but you may have some digits cut off, so your paragraph may look like this:

THIS IS A GRAPH:
10
9
[image that shows a graph with vertical axis that has part of 9 cut off, and no 10]

Mobipocket will show this:

THIS IS A GRAPH:
10
9
8
7
6
5
4
3
2
1
[Image that shows no text labels on either axis]
1 2 3 4 5 6 7 8 9 10

You can experiment. Ultimately it is the lesser of two evils. I have found that acrobat does a better job on complex documents. But only Acrobat 9 Pro can handle images, and for that you have to pay $$ or obtain it through other means.
