I also tried this program, with basically good results. I offer all of our books in HTML format, and it's a simple matter to select a file, then download the resulting ePub version.
I read it in the FBR reader with no difficulties at all. This program doesn't include graphics, so it stripped my beautiful cover, and it ignored my <center> and <p align="center"> (deprecated) tags. Otherwise, it seems like a nice little gadget.
I hadn't really messed with the FBR reader before. I installed the windows version with no problems and was able to read ePub and Palm DOC eBooks with no problem. I haven't experimented with other formats.
