I almost know it by heart. If you save it "to disk"--that just means you can save it to any of your personal files you want (instead of opening it), you can watch it any time yoiu want, no wait.
There is a "Cold Case Files" series running on A&E. It;'s very different. they are true to life stories, with a narrator, lots of dates, and a maximum of objectivity. They are real stories. I went looking there because I saw another Cold Case video, "Strange Fruit," which also looked great..; This A&E show is not artistic, tells no story, and has nio points to make, except that some old murder got solved. I do not recommend it. They are NOT re-runs of the "Cold Case" on CBS....that I can tell.
