I am meaning me, not you. A long time ago, my decision was, not
to use or support seminar. Especially I dislike the use of
\mag. It complicates the unit handling unnecessarily.

Here the rotated stuff is not needed, the generated orientation
is the correct one. But you have to set the origin and page
dimensions to *true* values:

\AtBeginDocument{%
  \pdfhorigin=1truein
  \pdfvorigin=1truein
  \pdfpagewidth=297truemm
  \pdfpageheight=210truemm
}
\documentclass[a4]{seminar}

% \input seminar.bug
% \input seminar.bg2

\begin{document}

\begin{slide}
\centerline{Slide Test}
\end{slide}
\end{document}
