I´m from Brazil and we´re trying to get Tivo working here.
For now we have Series 1 anda Series2 < TCD54x working (www.abandonemicrosoft.net/brtivo).
We´d like to have TCD54xx and newer working... but for that we need to hack HW (PROM)... could you help us sending your HOWTO about how to do it ?
Or if you charge for it... please tell me how to pay you (paypal?)
