That is incorrect. The Kobo devices do an excellent job of displaying epubs and changing the font sizes and other settings. Unless the person who created the book did stupid things. The ePub renderer, courtesy of the Adobe RMSDK, respects the styles in the book a bit more than most other renderers. This means that if the book creator hard-codes some settings, they cannot be overridden. Or results in worse looking books. The kepub renderer will override different things, and generally, I find doing this results in a worse result.

but in the past i could easily convert to kepub and use the nice format options then. i converted the harry potter collection to kepub (all newest calibre and plug-ins and kobo firmware) but it simply doesn't show up on my kobo at all after placing it on the device. every other newly converted kepub shows up fine, and i can read this ebook in the viewer app in windows.

is there something in the conversion or perhaps the original epub that would be causing a problem? I've tried conversion with every setting that strips formatting, clears excess junk, etc. i realize it could be the reader, but i can convert anything else even after trying this one and it shows up fine.
Of course errors in the original epub will cause problems. What and when depends on exactly what you are doing. But, the first thing to do is to check the book is actually on the device. If something went wrong and it didn't actually put the book on the device, then the device can't read it. Did the conversion work and produce a kepub in the library? Were there any errors from the driver when you sent the kepub to the device?

If you are actually using the KoboTouchExtended driver to transform the epub to kepub during the send-to-device, rather than doing a conversions, there are options in the driver for what to do if there are errors in the book. This can be to fail quietly and not send the book.
