On: MythTV 33 Released – open-source all-in-one DVR

That's interesting. I setup a new MythTV box two years ago on a Mac mini running Ubuntu, using a Hauppauge HD PVR 1212 capture device connected over USB. I've been able to record HD cable without dealing with any DRM by using the RCA jacks of my Comcast box, which has worked great.

How do you change channels?

A common solution is to use an IR Blaster: https://www.mythtv.org/wiki/Using_an_IR_Blaster_with_MythTV

I did something a little different. My cable box has a 3.5mm TRS jack to connect an external IR receiver to it. I connected the jack to an Arduino, and send serial commands to the Arduino from the MythTV box to change channels.

Very cool, thanks for the info.
