But my real problem is that when I do go into history and see why something's not going to record, it only tells me one of the shows there is a conflict with. Since my tivo has dual tuners, there should be two shows. But maybe the tivo isn't capable of listing them both for some reason? Hmmmm...
I've noticed this on my DT also: When there's a conflict on both tuners, recording history only lists the higher-priority one. You have to scroll down to the date/time in the To Do list to find what the other conflicting program is.
It would be nice if it could list both programs instead of making you do that.
Sometimes, of course, as gastrof describes, there actually only is one conflicting show b/c both programs you're asking for need the cable box. You can infer that from RH if you look at the channel number of the show listed as a conflict and see that it's a box-requiring channel. But it could be a lot clearer.
Ideally, RH would distinguish between these situations. It could say either "Program xx is not scheduled to record because Program yy will record on tuner 1 and program zz will record on tuner 2" or "Program xx is not scheduled to record because Program yy will record on tuner 1, and program xx and program yy both require the use of your cable box" -- and then you wouldn't be left wondering exactly what the issue is.
