[The attraction of an open source equivalent to TiVO is that may drive

demand

for bandwidth as users share and swap recorded TV files with the

distributed

architecture used by these devices. Excerpts from Wired magazine

article - BSA]

http://www.wired.com/news/technology/0,1282,59088,00.html/wn_ascii

Thanks to several open-source projects, you can build your own digital

video

recorder that will blow boxes from TiVo and ReplayTV right off the

shelf.

About a dozen collaborative software projects are in the works that will
transform a spare computer, or one built from off-the-shelf parts, into

a

homemade digital video recorder, or DVR. They also can record multiple

shows

simultaneously, archive shows to video CD, play digital music and

computer

games and display photographs and local weather forecasts.

Thanks to the combined expertise of about half a dozen hackers from all

over

the world, the project is close to assembling a complete software

package for

homemade DVRs. Version 0.9 of the MythTV software is due out next week.

Based on Linux, the free software features an easy-to-use graphical

interface,

which can be navigated with a standard remote.

The MythTV software offers all the basic DVR features -- it can pause

and

rewind live TV, and fast-forward through shows and ads. It supports

multiple

tuner cards (and multiple simultaneous recordings) and boasts
picture-in-picture capability if there's more than one tuner card

installed. It

also offers basic video-editing capabilities and allows shows to be

archived to

video CD.

MythTV grabs programming information from the Net using XMLTV, an

open-source

project that scrapes television listings off the TV Guide website.

For example, Raffi Krikorian, author of a forthcoming book called TiVo

Hacks,

is planning to build a MythTV DVR from scratch that will record two

shows at

the same time, store about 250 hours of programming, play DivX movies
downloaded from the Net and archive shows to video CD. The DVR also will

record

radio and play MP3, Ogg Vorbis and other audio formats, while grabbing

free

programming information from the Web.

MythTV has a nifty distributed architecture that allows multiple

machines to

work in concert, recording and streaming shows to each other over a

network.

There are about a dozen home-brew DVR projects, all based on Linux.

Others

include Freevo, eBox and the Dave/Dina Project. Krikorian said MythTV

was

probably the most complete and up-to-date. A list of the projects can be

found

at the Linux PVR Depot, which also maintains a database of the hardware

used by

various people.
