I have been trying to get my new Roamio to work with premium channels and I had the infamous VOD freeze problem. I am on my 5th Cable Card. Tried the Comcast CableCard number over 30 times to get it to paired. Tivo Support was all over the SNR numbers. I ran across a suggestion on a Tivo Board and it worked....so after a month trying, the solution was rather easy.
First, Logon to your Comcast Account and select Services (in the middle top) and then Equipment on the Right. The card in your Roamio must show up as MOTOROLA TIVOPMHST
On the COMCAST site for my ACCOUNT, my TIVO box was showing up as:
Make & Model: MOTOROLA MOTORHOST
On Tuesday I sent a e-mail to the comcastcares e-mail address asking them to change the make and model to
Make & Model: MOTOROLA TIVOPMHST
I also provided them my CableCARD ID, Host ID: 035-013-723-471-1, Data,
UnitAddress, and Card S/N.
I asked them to make the change and re-pair my equipment. And, I didn't need a call.
On Wednesday morning, I turned on my TV and VOD worked like a champ. I tried my premium channels, and they too worked like a champ. I logged on to my Comcast account and my Make & Model was now correct.
My SNR is still 42 and my signal strength is still 100%. So those who say the problem is on Comcast setting side are 100% correct. And, this is a good way to verify they have you configured correctly.
