I've got this Blu Ray Recorder, and I think it's fantastic (except for the ice age it takes to turn off, and hence turn on again if you turn it off by accident).  However, since playing a couple of Blu Ray's recently, I can't say I noticed a huge difference between a Blu Ray movie and and DVD movie when played on this unit.  That's not to say there's no difference - sound is definitely better, and the pictures seem a little brighter.  But I can't say the pictures have leapt off the screen when playing a Blu Ray.  That made me wonder whether the unit is simply doing an amazing job of upscaling, or whether the difference between DVDs and Blu Ray is just the marginal differences like better sound, and brighter picture. 

It's useful to know whether it's the format or the player - if it's the player, then unless there's a content reason to choose the Blu Ray when buying, or the price is similar, then I guess it makes sense to keep buying DVDs.

Anyone else with this unit want to comment on its upscale abilities?
