I currently have a Series 3 with 2 Comcast cable cards ... works GREAT! I'm thinking of moving to Dish Network. Their sales guy said that their VIP Duo 222K receiver can be hooked up to a Series 3 and it records fine. The TiVo support people say that only S1 and S2 receivers work with Dish boxes. Who's right? I don't want to have to shell out more money to get a Dish DVR if I don't have to! It's not that I don't trust sales guys ... :roll eyes: ... but I'd rather get info from someone who's actually done it. Thanks in advance!
