I have a Marantz VP12-S1 HD video projector & the only HD inputs are component & RGB. If I run AnyDVD HD on my HTPC will I be able to watch Blu-ray on this projector from the RGB output ?
Yes, if your HTPC has PowerDVD Ultra and meets the system requirements posted here http://www.cyberlink.com/multi/products/require_112_ENU.html.
You'll also need a Blu-ray drive for doing the rips. I also recommend getting a XBOX 360 HD DVD drive for ripping HD DVDs plus as much hard drive storage as you can afford.
