Use of @ sign in Guide data title

The program "At Midnight/@Midnight" is causing the Tivo guide processor to go NUTS. First of all changing the name from "At" to "@" screwed up the season pass; Recreating the Pass using "@" seemed to work, once. For some reason when the first recording added to the series folder it sorted to the Bottom of the list, a weird error for Record Date Order. Now the Pass LOOKS OK except the system puts the recordings at the almost bottom of the list but Does Not Update the record date on the Folder so you have to go to the last date before the Rovi change. The Folder also sorts under "M" instead of "At" or "@". I guess I should have known.

I posted this over a TiVo with no response. So...

Please fix this.
