MythTV takes Tivo to another level with the following functionality:
- Commercial skipping (remember when this was the selling point for Tivo)
- Plays any type of video from local and network storage
- Plays any type of music or audio from local and network storage
- Shows any type of images or pictures from local and network storage
- Plays DVDs
- Plays games
- Local weather forcast
- RSS news feeds
- Web browsing
- Telephone and videophone over internet via SIP
- Web based interface
And all this for free with no monthly fee, Wow!
I've gotten all these features to work with the exception of gaming and teleconferencing. With all these features it's not a simple program to install, but it sure is a rewarding project.
