comcast cablecard help

It's not provisioned/subscribed correctly. Comcast does not understand two tuners on the same outlet. I had WAAAAAAY too many hours on the phone with Comcast trying to tell them this and half a dozen truck rolls including an inventory trip by Comcast. One device on the same outlet does not compute. My bill is a mess, but everything now works and I'm being charged correctly FAIK. Additional outlet fees were being charged before. Their system can handle it. I now have three AO's free of charge on my account. You have to get someone from Comcast who knows Tivo to get it straight. Additonal outlet, $0 charge on the same cablecard is key, I think. Call them and discuss the situation and make sure they try different things on their system. It may change again after the 30- or 60-day automatic system sweep. Be persistent and patient.
