So I've been having the same problems as a lot of others apparently. It all started when I purchased a new Tivo Bolt. I previously had the Tivo Premiere. The Comcast VOD worked properly on the old TiVo but when I got the new TiVo I just took that card out and put it in the new Tivo Bolt. All of the channels came in properly but the VOD wouldn't work. I would get the CableCard screen. So, after unsuccessfully taking with Comcast support, they claimed it was a Tivo problem. I chatted, then called with Tivo support who did a three-way call with Comcast support. At that point Comcast support made some adjustments because the card wasn't pairing properly (apparently) and I was then able to access VOD. However, I didn't let it play long enough to determine that I was actually now getting the dreaded freeze after a couple of seconds. So, I then called back Tivo who sent me back to Comcast. I was "transferred" twice which must be Comcast code for hanging up on you. I spoke with two different people who insisted it was a hardware issue. I insisted it wasn't since the card worked fine just a few days ago. So I got a ticket and a promise to call me back. Ugh. So I tried the 888-824-8988 number listed above which is apparently advanced support for Comcast and I ended up with an American who seemed to know what my issue was. Corbin promised to call back in a few minutes after he corrected the problem. Well, he didn't have any luck apparently. He has escalated my call to their "Engineering" department who are supposed to call me back. Wasted my weekend on all this nonsense and still no resolution.
