Presumably, you're concerned only with the capture group (containing
the genre), so rewrite the expression along the following lines to
avoid the ambiguous/excessive backtracking:
p5c.compile("<span\\s+class=\"nametext\">[^<]*</span><br>[^<]*<font[^>]*>"+
"<strong>([^<]+)</strong></font>",
Perl5Compiler.SINGLELINE_MASK);
