Some queries re Tivo as I am contemplating getting one. I only use digital tv (via DTT boxes) as my analogue signal is awful. Can the Tivo control the DTT boxes in order to change channel to record different progs. Eg if I set it to season pass Enterprise on sky one and Friends on E4 will I need to manually change the channel on the digibox, or will the Tivo do it for me. Also, has the Tivo been upgraded to account for overruns on channels? Finally does it take an RGB feed from a digibox, and can it do RGB out? Id like to take the RGB out and use an active buffer and an rgb to s video converter to archive to DVHS. Finally Id only be recording (I suspect) at the highest possible recording quality, and hence the internal HDD might not be enough has anyone upgraded it with a higher capacity drive, or an additional drive (perhaps slaved to the master inside the box?) Any thoughts or answers are much appreciated.
