I added a login name and password and a port for remote access.  The port is 8888.  Now I cannot access the unit.  The name and password I entered do not work.  I think they may have a leading space but adding that does not work in the login.  when I enter in a browser, http://192.168.8.66:8888  I get the login screen for Tivo-web but in does not accept the names. I have opened this port address for this IP address in my router.  I can also ping the Tivo.

Is there a back door or default name and password that will work?

If not, how do I reset it so I can get in
