    I read the thread as basic dvr features TiVo should offer and nothing about the complexity of implementing said feature.

    I'd like to see some indication in the guide, marking shows that are already set to record. Like a highlight or a colored dot…?

    It's always seemed awfully strange that this isn't in there already.

    I think the Virgin TiVo video showed that in the new guide, but I may just be thinking of Media Center.

    Since at least one of the DTV HD DVRs did it, it's doubtful that it is patented. If it were simple, I don't think they would be able to patent it. If I were doing it, it would be simple in design, just not simple to implement on a TiVo since it would probably require a major change to the file system.

    Let's assume for the moment that a recording consists of a bunch of (probably doubly) linked blocks. Lets also assume that the TiVo knows what the first and last block are for each recording. You take a (hopefully) free bit in the block header or block allocation table and make it a dual allocation flag. When the overlapping recording starts, it sets the first block pointer for the new recording to the current block and also tells the system that it is using that tuner. System says "OK, that tuner is already in use. Until I am told differently, I will set the dual allocation flag for any block I allocate to that tuner". When the first recording ends, it sets the last block pointer to the current block and tells the system that it is no longer using that tuner so any subsequent blocks allocated will not have the flag set.

    When a recording is permanently deleted, only those blocks that do not have the flag set will be freed. Otherwise, the flag will be cleared.

    Take all of this with a huge portion of sodium chloride or perhaps potassium nitrate. I have no idea how the TiVo file system works or how it allocates blocks. Although I was an O/S analyst for 17 years, it was A) 20 years ago and B) on CDC* mainframes.

    For watchers of news programing, TIVO needs a switch that prevents the recording of multiple broadcasts of the same program title within a 24 hour period. Perhaps this could apply only to progams in the news category, or only to progams with identical and/or generic episode descriptions.

    Without episode data in the guide, most season passes of various cable channel news and talk programs result duplicate recordings.

    There's a simple solution for resolving recording conflicts - get more tuners! I've never run into any conflicts because I always had sufficient tuners available to record anything I ever wanted. My current HTPC has twelve tuners (eight digital cable and four ATSC), all of which can record simultaneously should the need ever arise.

    The main reason for so many tuners is because I pad everything I record. It's not so much of an issue with a Tivo but the clock on my HTPC can drift over time so padding is essential to avoid missing the beginning or end of a broadcast until I get around to resetting the clock. Still, I always padded my Tivo recordings because networks have a habit of changing their recording schedule on a moment's notice and the Tivo doesn't always get the change in time to make the adjustment.

    PIP is more of a function of your TV and doesn't belong in a Tivo, IMHO. You'd need to include additional hardware in the Tivo to provide two separate outputs or even to integrate a PIP composite image to the TV. Get a 2nd Tivo and connect it to the same TV and you'll take care of conflicts as well as have your PIP, too.

    Probably pointless to discuss since they aren't likely to do anything. But...

    With drive prices always falling they could just increase drive sizes and lower their estimates of how many hours per gig. Take the fudge factor and just duplicate the chunk from :59 to :01. MIGHT be simplier or fit their systems better...

    I set up wishlists on my HTPC in Media Center for all the new fall shows I wanted to record that had not yet appeared in my guide. I was going out of town for several weeks and had no other way to set up the recordings. Since I already knew what channels the shows were being aired on I could basically set up a future season pass by specifying the necessary parameters in the wishlist. Upon returning home from my trip I found that all of the shows I wanted to record were recorded and the new season passes were added to my schedule.

    I don't follow the rationale behind this. If a show is in hiatus (i.e., only airing reruns) you should be able to specify new shows only in your season passes. They have zero affect on what's currently in the guide so I see no point in deleting them, unless you have so many season passes that you exceed the Tivo's limit (100 SP's, IIRC). I typically have 50 or 60 season passes in my queue at any given time even though many of them are currently between seasons. Many cable series only air 10-13 episodes in a season and some only that many in a year. I see no reason to delete them just because they aren't airing new episodes at the moment.

    It's not the drive space that is the issue, it is the additional disk write stream.

    I realize wishlists are an option, but I don't want to clutter up the TiVo season pass manager with shows to air sometime in the future. The idea is to do it like Netflix where it is a separate list from the main season pass manager. The idea is more that the TiVo or at least TiVo.com should be aware of every show so you can make a season pass for that specific show even if it isn't in the guide.

    Also I have had wishlists miss recordings because of subtle changes to genre.

    TiVo doesn't have any limit on season passes I have found, but yes I am well over 100. It does make it more challenging though to prioritize passes the more you have though with KMTTG it is much easier.

    These days it is more and more common though to break up shows with multiple months of no episodes. By deleting the season passes you have the potential to miss when the show starts back up, but leaving it on clutters the list. For example we record I shouldn't be Alive. It just came back from a 2 month hiatus with no real notice. During those 2 months it is just a show taking up a spot in the season pass manager and serves no real purpose.

    Also this could be a way to create wishlists for shows without having the wishlists on the TiVo. You would just be prompted that show A is now in the guide on channel 5 and ask if you want a season pass. It would then send the season pass to the TiVo just like you requested it from the website that day.

    From threads talking about drives writting 2 more streams isn't going to matter on a normal premier- actually the elite proves that. (Could be an issue on elite but I forget the exact numbers- seem to recall 22 streams would be fine but might be my imagination)

    Also its not time critical. The tivo cocould copy the extra blocks a few seconds later and wouldn't matter.

    Anyway they wont do it so not really worth wasting too much of our time discussing.

    That's a good point itself. TiVo isn't leveraging their cloud except for ads and artwork.

    They could even use their servers for a limited cooperative scheduling. Their server could find out when something won't record do to conflicts and then record it as something less than an explicit recording but more than a suggestion on your other boxes. Would be better than nothing.

    DirecTV has a very simple implementation of back to back padding. It authomatically adds few minutes to the end of the show 1 and beginning of the show 2. It uses single tuner to do that, just splits the recording block in two places and ads a midle segment to both recordings.

    In addition to the "upcoming episodes" list I believe the Premiere has the same "episode guide" feature that the TiVo Search beta (for TiVoHDs) has.

    That list shows you every episode (sorted by seasons) whether or not they're currently available on tv, amazon, etc.

    Yes, but for the current season it only shows what has already aired and what is in the guide data. IOW, "episode guide" doesn't know any more about future airings than "upcoming episodes" does.

    You should be setting your clock regularly. There is no need for the clock in a pc to drift. Mine are set every hour.

    It is a known issue with the Microsoft time servers though that may not be his problem. Windows tends to be setup as a default using the Microsoft servers to sync. The Microsoft servers seem to not keep the most accurate time and it becomes instantly obvious if you are using the PC clock for your recording schedule.

    Yeah, that's what I was thinking. To invest in (and be forced to administrate) an HTPC with twelve tuners (!) to make up for the fact that the computer's clock drifts? And then relying on those tuners until the owner can manually reset the clock?

    #1, why is the clock drifting in the first place, so regularly? That would bug me and I certainly wouldn't see buying more hardware as a sensible "solution" for that.

    #2, surely you could use software that synchronizes with atomic clock?

    Surely then there's a way to select other, more accurate servers to sync withÂ… or a way to use some other utility to achieve the same result?

    If not, well, I'd avoid using an HTPC for that reason out of principle alone. When I want to watch TV I want a DVR that does all the work for me. I do troubleshooting all day. Even if it means I miss a show here or there, or the beginning/end of a show is cut off by a minute or two. I certainly don't intend to install 12 tuners in a box that can't even keep accurate time, that's for sure.
