DVD+R / DVD-R was a total crap shoot. Each media carried idential amounts of space and really had no difference.

Blu-Ray vs HD-DVD ... one is 50GB, the other is 25GB. There's the difference. The only way HD-DVD will win is:

1. Though a price battle. Under cut on everything.
2. Create hardware for the multiple uses for the media ASAP. (computer drives, integrated tv sets, standalone recorders, standalone players, budget players, etc)

HD-DVD is inferior. Blu-Ray has the ability to pack 50gb's per disc. More Gb's = a deeper sound experience and finer colors. For now, both may seem identical, but give it a year or 2 when Hollywood is actually filming movies for next gen DVD purposes. (Spider-Man 3, Transformers, etc)
