I thought I knew everything about HD-DVD but I've never seen this product before! Can't imagine where the ebayer found such things?
Except that I have an (ugly, sorta useless) HP HD-DVD ROM drive in my closet I might get one of these for my "collection". Oh heck, I might get one anyway!
I have a used one of these. It's a slim drive in a nice metal case. I think they were close to $400 back in the day.
ive got one very similar, except mine actually has the ability to burn HD-DVD discs. I got it as a bundle with 3/4 discs. Never used it, and never found software that was easy to use to convert HD movies into the HD DVD format.
