Chinese eBook Reader ... not close enough

I was kind of excited when I saw this iPad software called "Touch eBook", which support uPDB and PDB format eBooks, like those provided by site like this one.  However, when I tried the app, I found that except the several books provides WITH the app, all the books I downloaded caused the app to go crazy.  It seems like there's some overflow problem going on.

I tried those PDB files on iSilo for iPad, and it was not working too.  In fact, I found iSilo has it's own share of craziness too.  It doesn't have good file management mechanism (like copy files into any directory I created).  Eventually, I decided to just leave all magazines on the root of the directory structure.

At the end, I am settle with the app cBook Reader.  The operation seems a bit odd, and I find it strange that I can't directly load books from iTune, but at least it has directly way to download books from site, and once downloaded, those books work properly on the app.
