I´ve read in the c´t (the German Computer Magazine) that the iLiad only supports PDF 1.2 and less.

What happens with higher PDF versions. What is about an update to a newer pdf version?

You can open pdf 1.6. Tags that are not support are ignored.
[you can't playback a embedded sound file, pdf notes are only visible as icons etc.]
iLiad's pdf viewer can't handle jpg2000 stream, so it doesn't open this file.

[EDIT] iLiad's pdf viewer will not open pdf file if jpg2000 is embedded on page 1.
