    I don't think it is unreasonable to guarantee there will be no glitches. If you you are using a deposit-transfer to a device like a TiVO, it would not be difficult to include some form of checksums to verify the data stream, and have the bad blocks re-acquired on the next broadcast cycle. I have no fantasy that one could guarantee a perfect one-time transmission.

    The point on archiving is not unreasonable. If I am doing my own archiving, the content provider has no expense overhead for manufacture, distribution, packaging, floor space, middleman profits. Also, an archived copy does not include any of the "extras" that some people buy DVDs for.

    At the same time, perhaps a two-tier pricing structure. Say $1 for direct view with a timeout/autodelete from the buffer device, and an extra $1 if you decide to archive it.

    As to hoarding stuff "I don't need", that is the very definition of a collection. Is there any point to people having rooms full of paperbacks, dolls, toy trains, model planes, or other such "memorabilia"?

I have no issue with a reasonable per-month charge to cover the cost of the maintenance of the transmission hardware.

    I have a feeling they're trying to create a market for the over-priced DVD episodes of TV series. Who in their right mind would pay $20+ for two episodes on DVD when they can get tolerable quality with an SVHS recorder ($4 for premium blank tapes), or use a capture card and crunch it down with their own DVD-R burner ($5/disk)?

    This isn't about preventing "piracy", it's about finding a new way to steal a few more dollars from the consumer.

    Personally I would have less issue with a pay-per-view approach provided that:

    1. Price per 1 hour episode is no more than $1
    2. No commercials, previews, ad-banners, or other such nonsense is included
    3. The data stream is 100%. No bullshit blurring, bitrate reduction, or other nonsense like DirectTV uses. If I gotta pay, I want unreduced 1080p (not 1080i), with full 5.1 sound.
    4. A guarantee that there will be no dropouts, glitches, etc.
    5. I can make a non-duplicatable archive copy using a durable media like DVD.
    6. No monthly service charges. If you want me to pay per episode, I'll only pay for what I want to watch, not for all the hundreds of hours of useless tripe.
    7. No time slotting. If I subscribe to a series, I expect it to be deposited for viewing or archive on a weekly basis, to be viewed when I have time and the inclination.

    All in all, I don't have an issue with protecting the content from wanton copying and redistribution. I'm rather shocked at the number of people I know who already see first-run theatre movies captured by DV cameras and transcoded to crippled-bitrate MPEG4; I can understand the content provider's concern over the issue as bandwidth increases.

    As to the advertising revenue, do these morons really think I buy anything because I saw it on TV?

    The TiVO units let you start recordings 5 minutes early; the UTV only lets you extend recording time. A lot of channels up there don't start at exactly the time they say in the listings, so you can lose the opening moments with the UTV.

    TiVO lets you record by time/channel as well as through the guide. If you know the guide is wrong (often the case for local channels), you can "force" the TiVO to record the channel/time you want. The UTV doesn't support that feature.

    There were other little nicities I noticed with the TiVO, but I don't remember them offhand (it's been a few months.)

    Personally I'd never recommend a UTV unit to anyone. Aside from the crash, there are just too many little functionality tweaks to the TiVO that leave the UTV a so-so imitation instead of a true competitor.

Some focus on data collection or OLTP performance (Sybase, for example), some on simple online queries (most do well at this), some on complex MIS reporting (DB/2 and Oracle), and a very few on data aggregation and warehousing (often not even an RDBMS.) If the vendor can't tell you what their design goals are, but tries to convince you it can do anything, you had best be prepared to either spend a lot of money tuning your application for the RDBMS, or on hardware in a potentially futile effort to address performance issues.

    Bottom line is to use what suits your needs. To paraphrase an old saying/questionaire:

    You can have it:

    1. cheap
    2. scalable
    3. reliable

    Pick any two.
