I wonder if it would be possible for Myth to store dual versions of 
encrypted HD content, one encrypted full resolution, one downsampled to 
SD resolution.  It could determine commercial positions using the 
downsampled version, and apply the markers to the encrypted data for 
commercial skipping.  It could display the HD content at full res 
through a cable card enabled decryptor that doesn't expose the MPEG 
stream to the bus, unless the OSD needed to be displayed in which case 
it would cut the HD and show SD with the overlays (do you really need 
full HD when the overlay is showing?).

Complicated, and uses much more storage, but it might be the only 
workable way to get commercial HD channels in a FOSS project.  A side 
benefit would be that you would automatically have SD versions for SD 
only frontends.
