To anyone who is interested, I managed to track down a DVD copy of the Immortal Story at the website below. It is simply a copy of the TCM broadcast, but there are no subtitles as I understand many of the other bootleg DVDs have. The picture is nice as well as the sound in most places, although there is the occasional hissing sound. They also offer an Ambersons DVD, but I didn't buy that hoping that soon an official release will come about. But, I'm pretty happy with TIS, so I might give that one a try as well.
