I just read up on this new SOny HDV deck with HD-SDI out. I also think they are now available. Has anyone bought this yet?

I'm considering it but the glaring question I have is if it can record HDV realtime via component inputs. It kills me that you can't do it via HD-SDI, but I'll even take HD Analog in if possible. I have FCP with a Kona card and can play the HDV off the timeline to the KONAs component analog outs, for me to render an hour long, HDV timeline takes 6-8 hours! I want a device to record this in realtime.

I have a feeling it can't but it's vague in the literature I've been able to find online. I'll bet its a copyright issue with recording HD via analog ins what with all the HD-DVD and Blue Ray movies out now.

I'm not really sure about this, but I think whether you've got the HD-deck or not doesn't matter, since you're exporting the timeline from FCP. FCP has to render the timeline to make it into the HDV-format (muxing, I think it's called). It's like you have to render a DV-timeline into an MPEG stream when you want to burn it onto a DVD. HDV also uses GOPs and thus takes a long time to render from the timeline.
Only a the processor power will increase over time, will the rendertime go down.
