    Clipping is turned on, but again, every other show that recorded was a suggestion. A suggestion should never clip an actually-scheduled show.

    If they were going to do this they would have done it years ago, it's just not important to them (or is too difficult to incorporate into their file-handling code).

    I think a lot of the software devs here fail to understand why they can't do this because the fix appears straightforward from the outside looking in, but they have their reasons.

    It would have to be done realtime though which I don't think it possible given the processor power. And it would definitely require rewriting the database system used. It would be an large amount of work for sure and I'm not even sure it could be accomplished in a way that was user friendly.

    You have no idea what it would require, any more than I do.

    I think I do. The change would be a 10 minute fix. To be stable, tested code, much more work. Changing the code would require a large amount of testing to verify. I built stuff that, if wrong, would kill people. ****ing up Tivo isn't that level of seriousness, but maybe the engineers at Tivo have my mindset.

    I know what type of hardware is in a TiVo and how it can process video. There's no way it is a simple fix. Even on a powerful PC this is more complicated than people want to believe. Sharing data chunks adds so many more conditions that have to be accounted for, that if someone thinks this is a 10 minute fix, they are sorely mistaken. So if you want to play a video but are given a message that you must wait while the TiVo processes a chunk of video from a previous recording, I'm sure no one on this forum would complain about that either. :)

    Well, you could say that about other things -- they finally added a capacity gauge (though IMHO in an almost-useless way, but at least it's there).

    I'm not saying I actually think it will be implemented.. but survey questions do make me think about DVR functionality rather than new stuff that I will rarely if ever use.

    What does the DISH DVR do when you save a recording from primetime anytime to "permanent recordings"? Does it make a copy? Is there a delay?

    I do think that this issue could be fixed in a variety of ways.. the simplest being actually duplicating the video.. (who knows, even prevent you from watching the area with the duplication until it's done copying).. Other more sophisticated ways being essentially ref-counting the video, so there is only one copy but multiple files refer to that minute of overlap..

    Regardless, I would pay $100 per Tivo for this simple function, even though I already have lifetime.

    What would be a useful way for it? I thought it did what people want? It shows how much space is left by a percentage, which is all that most people would understand anyway. Of course there is no way to know how much you can put in that space since equal length recordings from four different channels can all take up completely different amounts of space.

    I realize that different channels can take up widely varying amounts of space.. So given the existing hardware(*), doing something like what the System Information screen tells you would be useful.. I am making up numbers.
    You have 10 hours of highest possible HD recording
    You have 30 hours of typical HD quality
    You have 60 hours of typical SD quality
    You have 300 hours of analog basic quality

    Word it slightly more user friendly somehow.. Basically, a time amount as well as a percentage amount.. I use the free space meter on my hard drive/DVD recorder MANY TIMES A DAY, to know if there's enough room to record what's going to record (nowadays, mostly analog backup recordings, and things I dub from my Tivos). Yes, it has the advantage of recording at an exact bit rate, so can give me a close-to-exact amount of space left. (Actually, it *under*estimates it slightly, I'm not sure if on purpose. E.g. if it says I have 2 hours left at the lowest quality recording, I think I have about 2:10 left.. but I don't rely on that.)

    (*) Even though I am slightly a videophile in some ways, I wish the hardware OPTIONALLY worked like old Tivos, in that it could recompress the digital signal (realtime, just like obviously it does from the analog tuner on ones that have the analog tuner).. In that not-actually-true case, it could give an exact time. For things like music shows, I wouldn't do the theoretical recompression. But for most prime time shows, I'd probably recompress to the equivalent of analog basic. It would still look way better than actual channels in most cases -- as I prove when I dub to my XS32.

    Old Tivos had to do an analog-to-digital conversion to store it on disk, so you could specify compression. Tivos now get a digital compressed mpeg2 stream (usually) and the only way to do what you suggest is to transcode to h.264 which takes a lot of horsepower to do without custom SOCs.

    I've often wondered if their reasons are patent related....

    Actually, all but the Elite have an analog to digital converter.. You wouldn't really need to transcode it, *with slightly different hardware* you could essentially reroute the analog outputs back through the A/D converter.. That's what my XS32 does when you do rate-conversion dubbing (which is realtime of course).

    Yes it would be hokey, but would be useful for space reasons.

    Sorry to resurrect this thread, but I ran into something similar and thought best to add to this thread than create a new one.

    I'm confused about how this works as for the first time ever I ran into a similar problem in which two of my season pass shows had a minute clipped at the start of the program.

    The wrinkle with my setup is that I have a 4-tuner Elite but have one tuner unavailable so that TiVo Minis can watch Live TV.

    Here's the full gist of what happened;

    1. An episode of "The Office" was recording from 8:29 to 9:01 This show has a 1 minute pad at the beginning and end of the program.

    2. I had two season passes scheduled to record at 9:00 PM... "Hannibal" and "Elementary". Neither of these shows has padding.

    3. What TiVo did was clip a minute from BOTH Elementary and Hannibal.... but at most only one show should have been clipped.... I have three tuners available.

    Can anyone explain what happened? Should I shut clipping off? This was really annoying.

    No idea what the issue was but from what you said I wouldn't have expected it to be clipped since you have three tuners available for recording and only three shows to record. Personally I prefer not to miss any part of a show so I've always had clipping turned off.

    This doesn't answer your question at all, but I could swear that one or BOTH of Hannibal or Elementary "officially" starts at 9:01 (in your time zone, 10:01 in mine).

    Are you sure there wasn't something else clipping it?

    I'm sure. The only recording happening before those programs began was "The Office".... and, there was only one red record LED lit on the front of the TiVo prior to those programs beginning.

    TiVo is so dumb. It should be able to use the same tuner to record to two shows at once off the same channel for that one minute in the middle. I doubt it would be rocket science to do.

    You're right, this is probably my #1 wish nowadays (since we now have a "ton" of tuners).. But IIRC, NOT all other DVRs do this either. Some do, but some don't.

    Heck, at least when it *first* came out (I do not know if this has been fixed), Primetime Anytime on DISH did *not* properly save off 'padding'. (Recording all of primetime, then even "manually" saving off shows with padding on each end pretty much solves the tuner dilemma.)

    So basically, Tivo's not worse than most of them.

    Agreed. It just seems that TiVo should be ahead of the pack and held to a higher standard since they are selling a premium, "aftermarket" product that's not just another crappy MSO box.

    DISH's Hopper is a neat device, but it's basically a 2-tuner box, as PTAT uses one, so you're left with 2 tuners for everything else, I'd much rather have TiVo's 4 tuners.
