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.
