While I do not have a large enough understanding of each format to guage the neutrality of its contents, this podcast is damn informative.  

This particular podcast is put out by Larry Hryb, otherwise known as Major Nelson, who is the X-Box Live Director of Programming, but you can just think of him as a liason for the X-Box Live Community.

In all honesty, HD-DVD sounds more appealing to me, and with how expensive and detailed the manufacturing process for Blu-Ray is, it sounds as if HD-DVD is more appealing to the disc-pressers as well.  I still think it's far too early to be pushing out a new media format, but I might pick up the HD-DVD player for the X-Box 360 if the price is right.  Hybrid discs for the win!
