When I was watching videos on »www.mtvmusic.com a message popped up warning about this. I didn't know if it was popping up for everyone or just people on TimeWarner/BrightHouse connections.
I have Comcast service, and I also got the scroll regarding this at the bottom- I'd imagine TW/Brighthouse wouldn't let it be exclusive to their own network.
The ad said something like "call 1800 ? for brighthouse and 1800 ? for time warner and DEMAND (all caps) your nick network channels, must be 18 to call".
Considering that it is Viacom, I'm surprised they aren't advertising a 1-900 number for a buck a call, or wanting you to text message for a similar fee... -- Toolmaster of La Grange.
