Found this...

I purchased a DVD-R copy from a seller on ioffer.com and it's a good 9 out of 10 on the picture quality scale; quite reputable. Mine does NOT have the Universal logo at the beginning and it reads "copyright MCMXLI B.H.P. Productions" under the title, and from an inferior copy I purchased from a seller on eBay, which reads "copyright MCMXLI Universal Pictures," it seems that the opening murder (no spoiler, I assume, since it's at the very beginning) is a bit longer on the better copy. I just watched mine again yesterday and it holds up quite well. Good luck finding a good copy until a pristine pre-recorded one is available.
