Ok.......

Stage One: Loading the file onto your TiVo
1: First you have to save http://dvd-create.sourceforge.net/ty...yserver.ppc.sh onto your computer. Put it somewhere easy to remember such as the C: drive root folder.
2: Open a command prompt window and type 'ftp' followed by your TiVo's IP address (ie: 'ftp 192.168.0.32')
3: Type 'cd /var'
4: Type 'bin' (This sets the transfer mode to binary)
5: Type 'put' followed by the path to the tyserver file (ie: 'put C:\tyserver.ppc.sh')
6: Type 'quit' to disconnect from the TiVo

Stage Two: Installing TyServer
1: Telnet into your TiVo
2: Type '/var/tyserver.ppc.sh' to run the install programme.
3: Follow the prompts.
4: Type 'reboot' to restart your TiVo

The server should be operating properly after doing this. Make sure that you enter the correct IP when running TyStudio, otherwise it will try to connect to something that isn't your TiVo.

Hope this helped you out.
