I'm not aware of an easy way to do this. It's not as simple as copying a file from one TiVo to another: you have to 'export' the programme from one TiVo and then 'import' to the other. This is (or used to be) a slow process (e.g. 1 hour to export and then 1 hour to import it again for each film).
An alternative is to stream the programme to your computer and watch it there. TivoWebPlus does this, I'm not sure about plain TivoWeb. But the principal is the same: you download a file with .ty extension which you can then play on your computer or media centre. Things like TyTool and mPlayer will download a .ty file from your TiVo.
If there's nothing on this forum (e.g.
