You probably won't want to hear this, but I'll say it anyway...
That green screen error indicates your TiVo's hard drive has failed, and you will need a replacement.
I'm sorry to say that many people are having problems calling VM at the moment as waiting times can vary - posting on here isn't a direct alternative else the board would be absolutely flooded with (potentially) hundreds of posts a day with people realisting it was an alternative.
I can only suggest calling again.
