I upgraded (actually downgraded) to Quantum TV about a month ago and I'm having a lot of problems, contacted tech services and they blamed my VOIP phone and home wiring for the problems, and now they want to charge me is someone comes to my house to check the problem, so now I'm going back to regular HD DVR. I tried to switch to Comcast but they are worse than Verizon, they didn't show up for the installation and their customer services is the worst, so I'm stuck with Verizon.
