It's a nice feature. Dang TiVo for not having continued it with TE4 (a major reason I'm still on TE3).*Sorry, do you mean I can initiate transfer using TiVo menu? This new menu will appear when I select shared folder on TV screen?
Please bear with me, I was using TiVo for years but never suspect existence of this ability.
Under your TiVo box My Shows list (or through using the My Shows Devices shortcut), select the share folder (the PC folder set under pyTivo Desktop/pyTivo as the source for shows that the TiVo box should look at). You then will have a list of the shows on your PC, in that folder. Select a show. You then will have a TiVo show listing for the show, with a menu option on that screen to transfer the show from your PC to your TiVo box, which you would select. Sorry if I confused matters by collapsing the directions at the end, earlier.
* There's a small (but probably unlikely) chance it could be brought to TE4.
