Question about when tuners are full

First post in this forum - I believe this is a very simple question, and will make most of you roll your eyes. Be gentle. :-)

Used a couple of TiVos years ago - loved them. Went with Cox's Record 6 a few years ago and thinking about coming back to Bolt.

However, I'm spoiled on 6 tuners, and of course Bolt only has 4. Here's my question: If I have 5 new shows playing at the same time, I know it'll only record the 4 shows that are highest up on the Season Pass list. However, I seem to have in my head from past TiVos I had that if that 5th show repeats, TiVo would record it...even if I had the season pass as "record new shows only." Essentially, it would record the repeat since it knew it couldn't record it when it was new because of full tuners.

Am I crazy? Does it work that way? Or would I just have to know that I have to change the Season Pass for that 5th show to record "New and Repeat?" That seems like a pain. I realize I'm spoiled, but I have to think of these things. (I realize the Roamio Pro has 6, but too pricey.)

Thanks for your help, all. Back to your normally-scheduled deep TiVo questions...
