I've got a Tivo V6 box and an older Tivo box connected through the Virgin router using ethernet and powerline. I have no problems watching recordings on the Tivo box via the V6 box. However whenever I try to watch recordings on the V6 box via the Tivo it works for a short while and then stops due to connectivity problems. It gets a bit annoying when it happens every couple of minutes. I've tried rebooting both boxes, the router and the powerline plugs several times, but this doesn't solve the problem. Are there any settings I should be checking, or will I just have to replace the Tivo box?
