Have you tried setting a redirect for /tivo to /tivo/ with the .htaccess in the document root? 
http://httpd.apache.org/docs/1.3/misc/howto.html
You could just redirect /tivo to /tivo/ using the .htaccess I'd think. 

Interestingly, my Apache server(s) redirect from /dirname to /dirname/ anyway, but that might only work if the dirname is an existing directory on disk, not sure. I'm not familiar with the mod_proxy_html syntax, but this seems odd to me: 

>          ProxyHTMLURLMap         /       /tivo/
>          ProxyHTMLURLMap         /tivo   /tivo

Might that work if you just changed that second line to read

          ProxyHTMLURLMap         /tivo   /tivo/
