If they woudl do with Blu-Ray what HD-DVD tried, puting the HD on one side of the disc and the regular DVD on the other, I think Blu-Ray would gain more market share, especially if the dual disc was the only version released. Once someone owned several of the dual discs, they would likely get a Blu-ray player. As far as rentals go, I do rent Blu-ray from Blockbuster and Netflix. My biggest problem is that there isn’t enough of a selection on BD. I’m anxously awaiting all 6 Star Wars movies and the Lord of the Rings trillogy on BD.
