mythTV, the open source DVR project, just released version 0.25

Although we may not be known for using a witty naming scheme, and the version number only increments itself by a single “hundredth” every major release, we’re extremely proud to announce the immediate release of what we loving refer to as – “0.25″! It’s been 516 days (that’s 1 year, 4 months, 30 days) since our last major release, so it goes without saying that a significant amount of work has made its way in to this current release with over 5200 commits making up 0.25.

MythTV version 0.25 includes several significant new features. A few key items to point out – new video acceleration capabilities such as VAAPI and DirectX Video Acceleration 2; expanded and improved audio capabilities including E-AC3, TrueHD, and DTS-HD support; Control your TV and other AV components via CEC (Consumer Electronics Control); enhanced and integrated metadata management capabilities for recordings and videos, and a fully functional API for third-party apps to build upon that can interact with both the frontend and backend – including a HTTP Live Streaming capabilities for delivering video content, in real-time, via the API.

Also noteworthy – MythMusic has been completely re-written and MythVideo is now directly integrated rather than being distributed as a separate plugin. Additionally, MythThemes is no longer maintained as a separate repository – all themes, including third party themes, can now be downloaded directly from the frontend theme chooser.

Release Notes:

Hi, my name is Damian, and I'm tech gadget addict! Although I always had some interest in technology, it wasn't until I got my EX470 and more importantly found, that my interest became an addiction. My goal, aside from world domination and to see the Mets/Broncos win another championship, is to set up the perfect digital home where all my media is available at the click of a button.

Damian, I’d heard about MythTV before, but this new version (Windows version of .25 is due out today) w/hd audio looks interesting. Is MythTV basically like XBMC? Have you used it, and if so, any impressions? Also, it looks to support OTA tuners and has DVR capabilities.

Brajesh April 12, 2012 at 10:36 am

Looks kinda like SageTV based on these videos:

UI look dated however.

Hey Brajesh,

Supposedly mythTV supports CableCard tuners, but I am thinking it supports in the same way that SageTV did (so won’t support DRM’d channels)

I haven’t tried yet but it is on my list. HTPCs don’t quite excite me like they used to in the past, so haven’t been too motivated of late to really delve in to.

Yeah, I’ve been on the fence about trying out an HTPC with XBMC and mythTV, as both can do hd audio now. But, I’m pretty happy with PCH-A300 for 2D and jukebox and HiMedia HD900B for 3D, so haven’t jumped over. Still, the idea of having a single box for everything does have its appeal.

I haven’t tried 3D on HTPCs, but I haven’t gotten the impression that it is 100% spot on yet

IDK, for me an HTPC is too much work in the long run to maintain. I rarely watch 3D and with 2D I at least know that playback is practically 100% flawless without me needing to tinker or wait for something to go wrong (more important from the standpoint of my wife and kids using, I no longer get those calls at work :D )
