In this locked post (http://forums.cox.com/forum_home/tv_forum/f/4/t/2502.aspx) a user complained that the Trio guide treats sports as a live event instead of a series. ColleenD said she would pass along this suggestion, but it is 7 months later and the option still does not exist.
With my older Motorola Cox DVRs that did not have the Trio software, I could set it to record every time MLB Baseball showed up on NESN keeping up to 1 recording, and that way I would always have the latest Red Sox game recorded. Now with Trio, I see this is not possible and it has not been implemented in the 7 months since a previous user requested it.
Come on Cox, make this happen. It is annoying to have to setup all these individual recordings. You would think the new enhanced Trio guide would at least retain backwards compatibility with the older DVR software.
