    I know I've seen it mentioned before, but while I thinks it important to show all that date info in the display, the actual "first run/repeat" logic is not that at all, right? The only way it's GENERALLY useful for most folks has little to do with original airdate or literal first-run status, you just want to be able to identify if you've recorded this particular episode recently, right? That logic seems more complex when different airing of a show seem to show different guide data. How does Tivo do it?

    TiVo drives it of the First Run Date
    (Proven during the Stargate Snafu (earlier this year) and other times)

    So it just records one occurence of each orig. airdate in a 28 day period?
    I'll have to watch more closely. I assumed that when a every episode of a show only had generic guide info ("The crew of Voyager is lost in the Delta Quadrant"), that the other data, like orig. airdate, was equally generic, but never actually looked, so I couldn't understand how it knew what it had recorded in the last 28 day. (I just attributed it to Magic.)

    What would happen if two new episodes were originally aired on the same day (like occasionally happens during season premiers and sweeps and such?

    Basically the logic works something like this: (This is derived from posts and other things, I don't have access to TiVo CODE)

    28 Day Rule: The TiVo keeps an identifier of the show (be it the actually episode/series ID, or some sort of hash on the description). If a show is set to anything other then Record Duplicates, exclude if it is in the 28 day history.

    First Run: If the First Run Date is the same day as the airing (plus or minus a few hours to account for 2nd airings) and is not in the 28 Day Rule... Record

    Repeats: If it is not a First Run...

    No First Run Date Available: Treat as a Repeat

    In the Tivo guide data each series is assigned a unique ID and and each show is assigned a unique ID. For example, this season of Stargate SG-1 has a Show ID of "SH225421". The episode "Ripple Effect" has an Episode ID of "EP2254210202" and has an original air date of 01/20/2006. Once a Tivo records this episode (as identified by the Episode ID not the name or description) it will not record it again due to the 28 day rule.

    As far a two episodes running on the same day, they will both be recorded as long as the original air date is correct.

    No one seems certain or not if the R-15 even has a 28 day rule ? Does it ?

    It has "something" as duplicate episodes don't record...
    At least for one of my test cases (Dukes of Hazard). If it records the 5pm showing, it won't record the one that is at Midnight (or is noon the next day)...

    Either way... there is something there.

    Well this is sort of true. With say Stargate it plays twice in one night, if the first run was recorded and I watched and deleted the show then the second showing tht night would be recorded also. This has happened with both Stargates, American Chopper, American Hotrod, and another show or two.

    The ability to see the original air date as i can see on my phillips non dvr box is one of the most missed features now that I am using a R-15.. this in 1 quick look enabled me to see if a show in the guide was one I may have seen before.

    So as long as it's current in MYVOD is doesn't record, but if it's been deleted it does? Yeeck. Don't like that.

    Like Clint said, if you delete the 5pm show it will record the 12pm show. It seems to not to record the show only if it's in MYVOD. But, I swear once or twice it didn't record an episode that wasn't in MYVOD, but that could be the R15 missing the recording in general. It may not have the 28 day rule but at least it doesn't record dup's if they are already in MYVOD, that's a start.

    It is at least one way to avoid the 2nd recording on many of the cable networks...

    Hm. I've not checked (my bad) but doesn't the ToDo list have the history? If so, you'd think it would check against there. One more Tivo feature that was omitted to meet the release date? Or from (then) not wanting to violate Tivo IP?

    Yes the R15 does have a history but it's pretty useless right now. It doesn't give you any info at all about what happen like a history should, nor does it show you the correct date. It doesn't matter if you delete a show, power outage, etc... it will only show canceled and it only shows on the date of the show. So if you delete a show on the 22nd that was from the 19th the history will show that it was canceled on the 19th with no info about how or why.

    I'm not sure of the capacity of the history list. Mine only has 50 entries, going back one week.
