Our rule is the NO FOLDER option so that an recordings displayed in the common area are never erased by the viewer unless all who wanted to view it have seen it. Remember a single recording will have separate "bookmarks" relating to each Joey or Hopper so that multiple people accessing the recording for playback will their own/separate RESUME point.
Sadly the above is NOT possible with TiVo. No Custom Folders, and if more than one person (TiVo box or Mini) accesses the recording for playback, ONLY ONE "bookmark" is made for Resumption of recording, which means that if you stopped watching at first commercial, but later, someone else at their client stopped watching at the 3rd commercial break, that becomes the one and only resumption point in memory and you are SOL finding your place if it was not in an easy to find place in the middle of the action.
I really can't think of an EASY way to achieve your goal. If you are sitting at the DVR or, perhaps, Dish Anywhere, you can go to the Scheduled and UN-skip the next showing to air later that night, but that is heavy maintenance. I wonder if setting the timers from different clients/DVR's for the same show can make a difference is some way for this goal to be a bit easier. I notice that the system displays which H3 or Client made the recording. It would be great if someone experimented (I am too hopelessly occupied) and discovered if this makes a difference.
