Hi all

Im trying to trace problems I'm having with my TiVo remote, usually its the up arrow. Seems to have happened (well, from memory) since I entered codes into the remote to control my stereo and tv.

So, what I want to do is remove the codes (basically factory reset) the remote. I've removed the batteries for a min or so, but that doesn't work.
Does the remote require batteries to be removed overnight or something?
What method does the remote use to store the entered codes?
