The only way to burn HD DVDs from the Burn disc menu is if you have a bluray burner. If you only want them to be able to play back on a fairly fast computer and not on a stand alone Bluray player, try rendering to WMV, HD 8mbs 1080 30P setting and then burn that to a DVD, or CD if it fits. Most faster optical drives will play these back fine with Windows Media Player. Hope this helps, Danny Hays
