First, there is no such thing as 'HDCP protected content'.  HDCP is a 
handshake and encryption mechanism for DVI/HDMI, and only exists on the 
raw data stream between the video source, and the output.  Your cable 
box, commercial DVR, Blu-Ray player, computer running Vista, etc... 
applies HDCP as it exists the machine.  You can record HDCP protected 
video streams by running it through a HD-Fury, and then capturing it 
with a component capture device such as a HDPVR.

MythTV supports commercial flagging.  It will scan the video, identify 
what it thinks are commercials, and then you have the option of skipping 
past them during playback.
