The original (Series 1) TiVos had various apps added to them of which one was TiVoWeb. TiVoWeb was/is a web browser interface that can control many TiVo functions including recording.
TiVoWeb is also in the package that enabled the TiVo to run on the Aus/NZ servers and needs to be enabled by David Keegel. Try a PM to him for this.
There is a problem however as TiVoWeb doesn't work fully with the HD TiVos and some development is required however there hasn't been any emphasis on this.
