Late night on Saturdays/early Sundays the CBS flagship stations East and West have Cold Case, East also has Criminal Minds and Without a Trace in HD...
Thanks for the info, dfergie...looks like ION will be showing 3-hour blocks each evening, in order, starting from the beginning on Monday...great time to catch up all episodes in order, or archive for your collection, as I'm sure the music rights will prevent this series from ever being released on DVD.
