The problem is that FCC rules allow TWC to basically set CCI as they wish. There are a couple of exceptions for 0x03 (reserved for PPV) and unrestricted locals.
It is very unfriendly to consumers to set a blanket 0x02. The intent must be to cripple third-party devices and in turn make their own dysfunctional DVR more competitive.
Tivo isn't blameless in this situation--their multi-room viewing feature depends on making copies. They have known for years that most people can't use MRV because of the CCI issue but they have done nothing to implement a different strategy.
