Why Burning HD DVDs from Final Cut is useless

Some time ago, I ran in to a little issue when a client wanted their video project to be burned on Blu Ray. Prior to taking the job, I told my client that I don't do Blu Ray because not many people have asked. Plus I didn't own a Blu Ray burner to begin with but he insisted that he would take care of it. The other reason I dont do Blu Ray is that Final Cut doesn't really have Blu Ray setting, at least my vision of Final Cut Pro 6.06. Ive seen tutorials on youtube that shows that the Final Cut 7 does have the capability of burning on to Blu Ray. But since I don't have that vison, I have to work with what I got. I figured that Id just have to burn it on HD DVD in Apples Compressor. After encoding and properly adding setting thru Apples DVD Studio, I burned the video on a DVD +R.
Once burned, I played the dvd on the computer. It looked great.
Everything went smoothly, or so I thought anyways. I ejected the disk and tried to play it on a normal dvd player. It would not play. ERROR in big letter pop on my TV screen and I didn't know why. It worked just fine on the computer, it should work on the dvd player. I tried to investigate this problem on the web, hoping to find an answer. I found that I wasn't the only video editor with the same ERROR on his screen. With no defining answer on the internet, I turned to a close friend, fellow video editor and all around techy dude. He told me that HD DVD is not gonna work because Im not playing it on an HD DVD Player. Makes senes.
My friend then went on and told me that the HD DVD would not work on Blu Ray either. Since Blu Ray won the war of HD Disk format,HD DVD players have gone extinct and very few of them are in stores. "FUCK!" I thought to myself. So what can I do?
Well I could upgrade to Final Cut 7 but Im broke and in need of cheaper solution. I do have though Toast Titanium, which does burn Blu Ray. I needed to upgrade the vision but it only cost $20 bucks.Here is a link to the steps http://www.youtube.com/watch?v=L3IDhivbu8k. Not bad. Still buying a Blu Ray burner and Blu Ray Disks costly. Like I said it is rare that my clients ask for it. Also the way things are going most people want their HD video uploaded on to the web, to be displayed to the rest of the world.
