How do I start developing a PC Program for TiVo?

I want to develop a program to run on a PC which accesses and downloads the whole Program Guide to a PC so I can sort it like my old Series 2 Tivo used to in the "Find Programs by Title" section. I am not sure where to begin. I need to get much of the functionality of kmttg in terms of accesing the data, then save it to a text database where I can deal with it in VB (a language I am very experienced in). But the front end will have to be in Java I assume. Have heard there are SDKs out...
