MythTV, the open source PVR program, has released version 0.17. While 0.17 seems pretty low, version numbers in the open source world can be misleading. I'm not saying to base your new start-up on MythTV yet, but it's been in development for almost 3 years and works for a lot of people. If you're building your own PVR and handy with Unix, you'll want to take a closer look at MythTV.
Some of the new features in this release are:
- Support for playback on Mac OS X (no recording yet)
- "Timestretch" to speed up/slow down video playback without affecting the audio of the pitch - Arrested Development at 1.5x won't sound like the Chipmunks
- Recording from Firewire HDTV cable boxes
