Not on my system. SDV is fine, though occasionally overloaded. I doubt this is a card issue... more likely a provisioning problem, or possible a faulty TA. If it's been working up until now, it's probably a "transparent upgrade" that TWC rolled out recently that is responsible for the problem.
Claiming it to be a TiVo bug is an excuse to walk away from the problem and stick you with it.
