The pcHDTV cards can capture OTA signals and, by some accounts, 
unencrypted QAM cable content.  Whether your provider delivers the HDTV 
content to you via unencrypted QAM is questionable.  That being said, 
probably the best way to get HDTV into your Myth box from a cable 
provider is firewire.  Get a new cable box with firewire outputs, make 
sure the cable provider outputs the HDTV content unencrypted via the 
firewire port, and you should be good to go.
