Hi Damjan,
the following code does what you asked for:
\documentclass{minimal}
\usepackage{xcolor}
\usepackage[matrix,frame,color,pdf]{xy} % or "dvips" instead of "pdf"
%\usepackage[all]{xy} also works for pdfLaTeX
\begin{document}
\begin{displaymath}
\entrymodifiers={=<0.5pc>++[o][F-]}
\xymatrix at C=1pc @R=3pt {
*{r} & *{s} & *{t} & *{u} \\
\infty & *=<0.5pc>++[o][F-][F*:yellow]{0} & \infty & \infty \\
*+<1pc>{} \\
\infty & \infty & \infty & \infty \\
*{v} & *{w} & *{x} & *{y}
}
\end{displaymath}
\end{document}
If this does not produce the yellow background disk on your computer,
please update Xy-pic to the newest version (currently 3.8.5). I do not
remember which Xy-pic version contained the xypdf version 1.4, in which
I introduced the color support for the xypdf driver, so your Xy-pic
3.8.2 might not have this functionality.
Best,
Daniel
