If anyone is interested I have created a simple TiVo net remote for Windows 7 which works with the VM TiVo (except for the coloured buttons as I cannot find the code for those yet).
Feel free to give it a try, have not managed to test it on anything other than my laptop, so let me know how you get on.
Basically a picture of a Vm Tivo remote which you can click on the buttons to send to Tivo.
You can also type on the keyboard to send text to search boxes such as when searching all tv. Typing numbers sends the Number to the TiVo.

Let me know how you get on. Plenty of improvements can be made after reading up on what can be sent.
You will need to have your TiVo connected to your home network, and have Network Remote Control enabled on your Tivo.
