In the past 10 days or so, Verizon FiOS has changed something on their end that flags certain channels with content that should not be allowed to be recorded and then copied. I have three TivoHD recorders in my house, each configured with a cable card issued by Verizon, and they are all networked together so Tivo's multi-room-viewing (MRV) feature can transfer a recording from one Tivo to another in my house. But as stated before, Verizon changed something on their end around June 6th or 7th that now flags certain channels as being protected.
When this happens, Tivo honors the copy protection flag, and prevents the recordings from being shared between my Tivo units. This sort of copy protection is usually limited to the premier channels such as HBO and SHOWTIME. But in the past 10 days this was turned on for many other channels, such as CNN, TOON, BRAVO. Some ESPN channels now have this, but not other ESPN channels. The random nature of this and the lack of protection on the HBO and SHOWTIME channels makes this appear to be an error on Verion's part.
Additional info on how Tivo honors the protection flags set at the service providers end.

There have been many other Tivo customers who are reporting this problem too. Apparently there was a wide spread cable-card problem around June 6th and 7th that may have accidently changed the copy-protection switches too.

Any help is appreciated as my calls to the FIOS customer service haven't gotten anywhere.
