Playback now available on any device

According to reports, the digital rights management (DRM) mechanism on TiVoToGo has been cracked, allowing users to use their TiVo to record video content for playback on other platforms and any devices. DRM protection on TiVo devices currently only allow recorded movies to be played back on specific Windows devices but now it appears that users are able to use a small tool to unlock the restrictions. The report suggests the tool used to remove the DRM system is coded in C and available to compile on various platforms such as Linux and Solaris.

TiVo originally announced TiVoToGo so that users could record programs and watch them through a network connection using the HTTP protocol. Currently there exists a wiki dedicated to the development of the DRM removal tool. From the wiki, a user that appears to be involved with the actual development indicated:

One thing you have to look out for is that you have to keep a turing "buffer" of the output of the turing code, one for 0xe0 (video) and one for 0xc0 (audio) and pick up where you left off last packet, not start over for each packet. And an audio packet can be stuck between 2 video packets with the same block id, so you have to have them seperate. I would post a link to the code I have written or put it on sourceforge or something but I am not sure on the licensing or whether or not I would get a goonsquad busting down my door ;)

The program is currently cryptic and difficult to use, however, some users indicated that those associated with the development process are working on a friendly front-end for average users. The tool analyzes header information from saved TiVo movie files and removes specific DRM header information, then dumping the raw MPEG data to another file. This creates a DRM-less MPEG file which is then playable on any device.

Nice.
Now why don't Tivo and other DVR just let us plug in our own USB hard drives to storage the data. It make no since that we can't use our own storage media instead of us having to rely on thier small 200GB drive systems.

If they want to "protect" the content, just encrypt the hard drive and add a disclaimer that it's not under their warranty/support. At least, I could add storage when I want.

P.S. No a fan of DRM.

You can just upload the movies to your pc...
It's hard enough as it is getting a wireless card to work via usb let alone HDD drivers, heh.
