I just wanted to post my experience of Comcast VOD freezing and my resolution is case it can help others. I went form Series 3 and Premiere both with VOD working. With the new Roamio, I could play VOD for 4 seconds and it would freeze. It took 10 days with at least a dozen calls and over at least 10 hours of my time to resolve the issue. I called Comcast cable card activation several times to pair and unpair my cable card without luck. I called Comcast customer service who kept resending the signal without luck. I asked Comcast billing to add the infamous Tivo sales code without luck. Tivo customer support stated that my SNR was to high at 39 db. They recommended placing attenuators to lower the signal because a hot signal may cause problems. I had Comcast come out and test my lines, no problem there. They added the attenuators, no luck either. After Comcast customer support could not fix my issue, they escalated my case to level 2 support and stated that I would receive a call back in 1-2 days. They stated they could not transfer me to level 2 support because they did not have the phone number. After 5 days and no call back, I called Tivo support back and stated what had been tried and that a technician came out and tested the line. This Tivo support representative had the number to Comcast level 2 support (which Comcast stated did not exist) and started a 3 way conference call. After a call back from level 2 support the same day, they finally figured out that my account was setup incorrectly. They stated it was set up for 2-way transmission, but should have been setup as 1-way transmission. I post this to help others who could have the same problem. I must say Comcast level one support is ridiculous, after not resolving my issue and retrying the same thing over and over, my case should have been escalated to level 2 support sooner. They should have transferred me immediately and not have to wait 10 days and waste my time. For a company as big as Comcast, I was very disappointed in how my problem was handled. Finally VOD works now. All is good again.
