Mythbuntu 是一份基于Ubuntu的发行，它是一张自启动运行光盘，着眼于构建一份单独的MythTV系统，这与KnoppMyth或Mythdora类似。它可以被用于安装一份独立的前端或后端或组合机器。Mythbuntu采用Xfce作为缺省桌面，它提供一份图形化的控制中心来配置系统。
The third alpha release of Mythbuntu 8.04 is out and ready for testing: "Today we are introducing the third Mythbuntu 8.04 alpha image. It is very important to note that this release is not compatible with Mythbuntu 7.10 or any other MythTV 0.20.2 based distribution. Changes from Alpha 2: lots of bug fixes across the board in Ubiquity and Mythbuntu Control Centre; several MythTV bugs that were sent upstream got fixed; we have merged our installer menu with the Ubuntu installer menu; Totem can speak MythTV now for playback; new version of XMLTV; new Myth checkouts; diskless support. As previously, if you encounter any issues with anything in this release (including Ubiquity), please file a bug on Launchpad." Here is the full release announcement. Download: mythbuntu-8.04-alpha3-i386.iso (520MB, MD5), mythbuntu-8.04-alpha3-amd64.iso (544MB, MD5).
