Hi, I just bought this used PTV 300 model Tivo. I already have a Dish DVR that I pay a subscription on. I bought this one to just use on my daughters TV with no subscription to Tivo. I just wanted to use it to use the Pause Live TV and maybe push record while watching TV and push stop when it finishes (that way I wouldn't need the subscription). Is this not possible? I set it up and plugged it in and got a "Your reciever is starting up please wait" message, followed by a "Just a few more seconds", and finally a "A severe error has occurred please leave your unit plugged in to the phone line for 3 hours" type of message saying to call this 1-800 number. Am I not going to be able to use this unit without a subscription at all?
