Roamio missing "Save until space needed" option

Just upgraded to Roamio from Premier and have noted that the "Save until space needed" option is not available for shows that have been newly recorded or transferred from the Premiere. Season Pass Manager has space needed option selected but it doesn't actually work. TiVo support was surprised at this but would only guess that the feature had been removed in a recent software update. Looking at the Romio manual online I see until space needed option mentioned under the "Setting a show's recording options" section.



Has anyone else noticed this? Seems like a very useful feature to have eliminated as I used it all the time on my Premiere.
