Advertisements UPDATE - Everything is working! as of last night, Comcast activated and paired the 2 cards that were in the S3 TiVo, so that TiVo is working perfectly now. The HDTiVo was not working last night, i tried the 8080 number this morning and a tech called me back 30 minutes later (while i was still home!) and told me to go check that tv and bammo, everything on the HDTivo was working! now the TV, it's a mitshubishi, and the tech on the phone said that it may not recognize MStream cards, so i am going to get a firmware update from Mitsubishi and see if that fixes it. But the bottom line is that the 8080 phone number is the fastest result i have ever gotten! The tech also said that since that letter went out they have been so slammed that activation does actually take up to 72 hours in some cases, he said normally it's a 4 to 6 hour process and it will get back to that once this whole swap out of cards settles down.
