Come on VM - plenty of people here with the exact same issue.
I have an Onkyo system and I have tried all 10 codes listed with no success. I then used the code search function like all these guys before me and it found a code for me very quickly, like all the others I'm afraid to say that I am having the same issues when I press OK to lock in the code it no longer works.
How hard can this be????
All the little things that are wrong with this TiVo box when rolled together make this a box that I would struggle to recommend to my friends - surely a fix must be imminent.
