Welcome aboard.

The TV/PVR functionality and the GUI/menu framework form the bulk of the
base code. Additional functionality can be added in various ways:
mythmusic, mythvideo, etc. are plugins (very simple/limited plugin
framework). You can also launch other processes, and configure the menu
screens via XML.

The core software is C++, based on the Qt library from Trolltech.

Well, if you want Myth to be able to access all the channels you're
paying for, you need to go through the set-top box. You can also plug
the cable directly into the tuner (in addition to the S-Video/Composite
connection from the STB) as a 'backup' video source; that connection
will give you channels < 125.

Lot's of chatter about different features, but nothing really concrete
yet in that area (music, you mean?). Someone has a working DirectShow
filter for playing Myth recordings in Windows; someone else (I hear) is
working on a Windows frontend.
