Nope. To the best of my knowledge there's no way to turn that off since it's basically an email from TiVo. At least the premiere gives you the option, IIRC, of deleting the message right from there instead of hitting "done reading message" and then having to go to messages and settings to delete it.
FWIW, I agree with you, I don't really care if they changed QGLFHD from 1412 to 1417, but I understand why they let us know. It's going to save the cable company a ton of calls from angry customers wondering where there channel went (or TiVo for that matter). Also, when you get a message that say SPTCHD was added, that's a bit of an advertisement. So I always wonder if it's something contractual.
