You will NEVER get the sharpness or accuracy from an A/D conversion of an analog signal to a digital represenation for painting a digital display. Even if you're only into gaming, you would still see sharper representions if the digital image is kept digital all the way from its generation to display. As for using HTPC's for displaying movies--forget about sticking a Blu-Ray player in your computer and displaying a HD-quality movie over a VGA line. Everything will be encrypted by HDCP and will ONLY pass over a DVI or HDMI link. If you only want to display current DVD's on your television-- I guess the Samsung would suffice-- its somewhat short-term focused though for alot of the readers to this forum.
Sure, keeping the signal in digital format all the way is the ideal solution. However, DAC and ADC have been done for a very long time, and are very simple to accomplish with great fidelity. It appears that you have never seen a Samsung 1080p set connected to HTPC via VGA. It is simply stunning.
Also, it will be a very, very long time before I will be able to put a Blu-Ray player into my computer at all. At the time being, Microsoft and Intel are planning to support HD-DVD, having declared Blu-Ray computer unfriendly.
As I mentioned before, the VGA input at 1080p is truly excellent for HTPC, and Samsung sets will be perfect for those folks who want to connect a computer and still have two free HDMI inputs. For the foreseeable future, 1080i into HDMI will be the norm for external sources, e.g., DVD players and set-top boxes. HD-DVD will output at 1080i (confirmed), and I believe that Blu-Ray will do the same once the dust settles.
The commercial success of new DVD formats is by no means guaranteed, and the format war is only making things worse. The majority of consumers may conclude that upconverted 480i DVDs look just great especially when they are produced well. In the audio realm, SACD and DVD-Audio ended up in limbo. To add insult to injury, compressed CD music (MP3) is gaining momentum big time. It remains to be seen just how successful the new DVD format will be (whatever format ends up being chosen).
Best of luck with your forthcoming purchase of external scaler. I am sure it will provide you with outstanding picture.
