I was just wondering if anyone knows a way that i can provide feedback to Tivo about the Caspa on demand?

I am only new to Tivo, is in i received the box 2 days ago, but one of the main reasons i bought it was for the on demand content, which quite frankly is awful!!
There is very little content and no options to view trailers, no search option (from what i can find) and did i mention very little content??
My Mum has just got a Telstra T-Box and apart from having a smaller hard drive it seems to have all the other features of the Tivo but with a MUCH better on demand selection as well as trailers etc...

Anyone know any plans to improve this?
