I think I have both a Tivo and a V6.
I posted a link to photos of the boxes in my previous post.
The older box has been struggling quite a lot later so maybe time for an upgrade.
If you're out-of-contract then it's certainly worth trying to negotiate an upgrade from TiVo > V6 for your second box. Just be very aware of a possible sales pitch for the newer TV360-software. It has pros & cons which are worth researching, but pne notable caveat in your case, is that a swap from TiVo > 360 directly will mean a loss of your second box's hard drive.
