I'm at wits end and I'm about ready to cancel service. Has anyone had success with Xfinity OnDemand with a Premiere 4? I bought a new Premiere 4 12 days ago. Got the cable card from Comcast, hooked it all up. I love the TiVo interface, capacity, 4-channels, etc. But the Xfinity has NEVER worked. I've now spent 12 days on the phone with Comcast tech support and TiVo tech support. Both support groups say everything is good on their side so it must be the other side's problem. I can access the Xfinity menu. I can browse through the shows/movies. I can select a show and it will start. But EVERY time, it freezes at 6 seconds. The time bar keeps on rolling along, but the picture stays frozen. I've switched out the cable card. I've re-paired them multiple times. Comcast sent the "signal" multiple times. Comcast opened a network ticket with engineering. Then Comcast told me the Premiere 4 isn't compatible with Xfinity (of course TiVo says BS). Comcast has reset new "rate codes" whatever those are. All of this and still no luck on Xfinity. I'm fed up. I'm within my 30 day money back window. I'm on the verge of cancelling TiVo and Comcast and switching to DirecTV and the new Genie system. Has anyone else fought this TiVo/Comcast battle? Did you get success? What was the secret?
