TiVo File Encryption Cracked 250

An anonymous reader writes "TiVo file encryption has been cracked. Details on the project can be found on the wiki. Mac and Linux users rejoice!" The project page says, "The conversion still requires the valid MAK of the TiVo which recorded the file, so it cannot be used to circumvent their protection, simply to provide the same level of access as is already available on Windows."

    It hasn't been "cracked", since it still requires your Media Access Key to decode the video.

    No, this just applies to standard def content from a Series 2 TiVo. You must use the Home Media Option to get the files off the TiVo top begin with. The Series 3 TiVo (the HD version) does not support the Home Media Option.

    Why "recall"? This is the Internet. Look it up.
    Sec. 1201. Circumvention of copyright protection systems

                `(a) VIOLATIONS REGARDING CIRCUMVENTION OF TECHNOLOGICAL MEASURES- (1)(A) No person shall circumvent a technological measure that effectively controls access to a work protected under this title. The prohibition contained in the preceding sentence shall take effect at the end of the 2-year period beginning on the date of the enactment of this chapter.
    I don't see any reference to who is adding the "protection". This is probably a DMCA violation.

    'Course, unless you run Linux but have never watched a DVD, you've pretty much already opened that door.

    IANAL, but while I'm sure you could argue either way, I'm pretty sure that the better argument is that the DMCA is intended to allow non-owners to add protection, as TiVo is here, for exactly the sort of things TiVo is doing.

    Check it out, and you'll be amazed.

    I did, and I wasn't. It was a giant pain in the a** to set up and configure, it didn't work reliably, and the cost for hardware was way higher than buying a TiVo.

    It won't. Series 3 do not have the necessary feature enabled because Cable Labs won't let them (yet). Look for it in a future release (if hell freezes over).

    For getting video off a Series 3, I worry that it will take an external drive (once they enable THAT) and then get the files that way.

    I say all this as a Series 3 owner who, really, doesn't have a ton of use for extracting video.

    In short: Series 3 need not apply.

    ...recording programs to a large hard drive and then being able to either play from the HD or else transfer them to a computer and burn DVD's of the stuff for permanent storage. There are standalone DVD burners (Panasonic, Sony, etc.) that have hard drives. You record to either DVD or the hard drive, and you can playback from the HD or record the data to DVD.

    Yes. Almost all video capture cards come with programs to do this -- every card I've had/seen from ASUS and ATI does. There won't be any program guide or fancy remote control, but it'll record whatever you program it to. Just like a VCR.

    The appeal of the Tivo is it's simplicity and ease of use. Yes, I can build my own, but it will cost far more than the cost of the tivo and monthly (or lifetime) service. Plus a home grown solution will tend to require never ending tweaks to keep it running.

    Yes it has. The MAK isn't the key to the encrypted stream- the MAK is what's printed on the System Information page in the TiVO.

    This defeats TiVO's DRM that was used to prevent Linux and Mac users from watching shows on their PC.

    It's a pain in the ass to set up and configure. I can't argue with you there. If you've done it once successfully, though (or two or three times) it becomes much easier.

    However, I take issue with "didn't work reliably" and "cost was higher than a tivo."

    My own MythTV works flawlessly, using a donated PIII-750 (cost: $0) for the server, and a Hauppauge 150 (cost: $60) for the tuner/encoder. There are no monthly fees. If you can show me a TiVo with lifetime subscription for $60, I'll be amazed. And tell my friends to buy it.

    My MythTV also has features that TiVo will never have -- like the ability to automatically detect and skip commercials, the ability to select programs to automatically burn to DVD, and support for enough tuners to simultaneously record everything on every channel (well, in theory... I'd love to see the hardware for that!).

    I like the TiVo. It's easy to use. But I like my MythTV a lot more. And I don't have to worry about what stupid decisions TiVo corporate might make -- like encrypting my videos so only I can watch them, support for the "Broadcast" flag, and wasting my storage space with advertisements.

    Apples & Oranges, the data you get from the disk on a Series 1 is no-DRM, unencrypted marginally proprietary MPEG-2, the stuff you get from a series 2 via Tivo to Go is DRMed and not easy to un-DRM, so you need a TIVO-annointed software component to read it, this is about removing the TIVO-annointed requirement ;-)

    This is an article about the BS associated with proprietary solutions. The possibility of using an open solution and BYPASSING all of this BS is very much on point. I am a LONG time Tivo user that chose to build a MythTV system over this very problem.

    or $5 for those long standing customers. For two tuners per unit. And in my case, in HD.

    Shortly I'm going to try to get a fusion card to work in HD-OTA with a new box, but don't kid yourselves on the costs. A tivo runs 40+ watts and costs about $3/month to run. An efficient PC is likely to be double that, at best. (the older CPUs - perhaps we're talking Athlons - burn 90-100 watts on their own.) The older machine will also need a new hard drive for the storage needs, esp for the HD crowd. Add another 60-100 there.

    13/month seems like a hard sell to me, but the dtivo units run way cheaper than the PC route, with the simple reliability that can't be matched by general purpose PCs.

    UPSs deal with power hits well, esp when the draw is only 40W. I can literally go an entire day. (OTOH, the hdtivo has been rebooting itself at ~2:30 the past two saturdays - very odd behavior)

  • Either you have a really crappy HD input signal, you don't have your TV calibrated correctly (get a video essentials/avia DVD), something else is bad (cables, malfunctioning part, etc), or you have a smaller TV and you are not sitting close to it; because I've never known anybody to say that it's not really that different when seeing the actual difference. (most often it's because they have their TV calibrated to make 408i signals to look better, which unfortunately conversely makes their HD signals look bad)

    Also, does turning the power off on a TiVo (not pulling the power plug or anything) actually stop the box from recording? I haven't had a TiVo in my house for about 5 years (been using MythTV and cable company HD DVRs), but I thought the TiVo would turn itself on and record when your shows come on.

    TiVo's don't have a power switch. The closest you get is putting it in Standby mode which stops video and audio output. The unit is still on and still records shows and LiveTV. At least, that's true for the standalone units which are what I have, and I use Standby mode to switch between them all the time.

    My problems with my TiVo arise from bugs in the latest software update for the cable box, causing it to fail to tune to the correct channel if you try changing it while the time turns over to the next timeslot. And sometimes (twice experienced) spontaneously on the hour without trying to change channels. It's not a TiVo bug; it's a cable company bug to which I'm forced to accept if I want digital cable, or switch to their DVR (that's anticompetitive behavior).

    I want an open source cable box with CableCard support and the authority to install a CableCard into any device I see fit, not just those on their accepted list. (I'd get a Series3 HD TiVo but can't justify the expense.)

    I know my P3-450 BIOS has a setting to wake at a specified time, but I don't know if that has a API to set it via software.

    It probably doesn't. The usual trick is to use nvram-wakeup to edit the onboard CMOS RAM and set the wakeup time that way...

    Infact, when stacked up next to a nice progressive DVD those HD channels aren't that hot anyways. Even when not compared to good DVD's in a side by side comparison those HD channels aren't that impressive.

    If it's good HD, that is just not true. Sure, for poorly encoded, or lower bit-rate transcoded stuff that may be so, but check out PBS-HD and tell me it's not better.
