First of all, sorry for the late reply. I never ever made an index
for a seminar document and was surprised it works at all ;-)

The reason for this does not lie with TeXPower, but with
a misunderstanding between seminar and hyperref when the
default setting plainpages=true is used: For constructing
page anchors, hyperref employs the counter "page" which is
used only for notes by  seminar. Slides are counted with
the new counter "slide".
When setting plainpages=false, hyperref uses \thepage,
which is redefined appropriately by seminar to yield
the value of "slide".

I wonder why you're getting numbers 1-5 at all, normally
the page counter stays at 1 ;-)
I assume these are note pages (maybe the index itself).

Summa summarum, the following simple example works for me
(running pdftex):

\documentclass[KOMA,landscape]{powersem}

\usepackage{makeidx}

\makeindex

\usepackage[plainpages=false]{hyperref}

\begin{document}
\begin{slide}
foo\index{foo}

\newslide

bar\index{bar}
\end{slide}
\printindex
\end{document}

Even with plainpages=false, there'll be a lot of
redundant warnings about destinations on pages
which are displayed incrementally, owing to a
quirk in pdftex. There's a new pretest version
under

ftp://ftp.fi.muni.cz/pub/tex/local/cstug/thanh/pdftex/snapshots/20000912/

which was just announced to remedy this problem
(I'm not planning to install it just for testing
this out, so I'll be happy to hear from anyone
who does).

regards
Stephan
