I dunno about any of your other questions, but a possible alternative to playback of HD material might be the WD TV Media Player by Western Digital - $129.00 solution some of the people on several forums are bragging or gagging about at present.
So popular that BestBuy sold out its stock on sale at $99 and all the stores near me are on backorder status. WD has a web site (Google it - WD TV Media Player, if you're curious). I'm reading user reports that video people are even putting their HD resources and demos on USB thumbdrives and enjoying the results. Impressive, IMHO.
So, if you get your stuff edited and ready to record the way you want, this might be a solution for playback, even delivery while the BluRay situation either comes on stronger, or goes away.
