Nary a bit. Some of my Tivos have shows that have been awaiting deletion for 3 years. I have quite a large number that are that old or considerably older: Only one has an oldest scheduled program less than a year old and that is because I only got the TiVo three months ago. Of course, I have archived many, many hundreds that are a lot older than that, but even on the TiVos I have a handful of KUID programs that are almost 6 years old: That can never happen on a TiVo unless one excessivley employs KUID, in which case lost recordings are a given. KUID in general does not prevent programs from being lost. Rather it makes it much more likely. All of my TiVos are virtually 100% full essentially 100% of the time, and they record up to 30 programs every day. I've never lost a recording, except due to my own mistake, or external issues like a power or cable outage or system lock-ups. That's really not relevant to this issue, although it probably does call for larger hard drives. If the TiVo hard drive is too small, then it limits the ability of the user to watch everything they want before some of it becomes in jeopardy of being deleted. For example, suppose the Tivo had such a tiny hard drive (or so little drive space left after KUID recordings are taken into account) that the user is recording on average a volume of shows that will completely fill the hard drive in 24 hours, then as long as the user watches every single thing recorded in less than 24 hours, then none of the content will be in jeopardy of being deleted. OTOH, if the user takes more than 24 hours to watch the content, then some *WILL* be deleted. It doesn't matter whether the amount of sapce on the drive is 100M or 100,000T, if only 24 hours of recordings will fit, then after 24 hours some recordings will be lost. Lets say the number is 10G, for a round number. Increasing the size of the drive so that no recording will ever be in jeopardy of being deleted does not require getting a 3650G hard drive. Indeed, it will only require perhaps a 300G or 400G drive. At some point, the TiVo storage becomes effectively infinite. Where that point lies is variable depending on the recording and viewing habits of the poeple using the DVR, so a family of four with active recording habits and very sporadic viewing habits will require a much larger drive than a single person who watches everything they record within a few days of it being recorded. Note the DVR will not create more time to watch, other than allowing the user to skip commercials. If the average amount your family records exceeds long term the average amount it watches, then at some point shows are going to begin to be lost, no matter how large the hard drive. As an aside, if it is the intent to keep any items (as opposed to just leaving the items on the TiVo) for over a year, it would definitely be a good idea to archive then until they are needed. Doing so with any frequency and certainly doing so habitually pretty much guarantees recordings are going to be lost. This, then may urge the users to set more KUID, which loses more programs. It is an absolute fact that the lowest number of lost recordings will be produced by setting nothing whatsoever to KUID. It is also an absolute fact that without KUID intervention, it will always be the programs that have sat on the TiVo the longest that get lost, and no new recording will ever fail to be recored due to hard drive recording capacity. Absolutely 100% guatanteed, no matter how many programs are recorded by how many people, how big the hard drive is, how many programs get watched in a given period, or how old the programs might be. WRT internet features, that may well be true, but WRT hard drive capacity and core recording features, I don't know whether it is, or not. What types of recordings one favors is of course a perfectly individual thing, but at a fundamental level capacity management has little to nothing to do with individual preferences or habits. The size and variety of the FIFO pool will vary a lot from one household to another, but the mathematics governing the realtiver behavior does not. I never made any sort of comment about that question. Indeed, as you can see above I have four TiVos, plus six different TVs around the house, so it would be a singularly odd comment for me to make. None of the TiVos or TVs are in bedrooms (unless one considders a convertible guest room to be a bedroom), though, and all I said is placing a TV in a bedroom can have significant and possibly serious negative impacts on one's health. Again, as any pulmonologist or sleep specialist will advise you, to promote good health, a bed should be used for two and only two things: sleeping and making love. Eating, reading, and especially watching TV in the bedroom should be avoided. Doing such things in bed promotes increased fatigue, sleep depravation, insomnia, anxiety, and depression.
