Got my DVDO today and was in brand new condition. My quick review. This scaler is advertised as scaling all inputs from 480i - 1080i and outputting to 720p, 1080i/p. I will say first off this scaler did a pretty piss poor job of up scaling 480i sources (Sat TV and regular DVD). In fact the instructions ask you to set your sat/cable to 480i for SD channels and DVD but the picture output was far too soft and looked horrible. It's when I set my Sat box and DVD player (Oppo 970) to 480p that the image really sharpened up and the scaler did a slight improvement on the picture than without the scaler. Nothing really to brag about but did slightly improve the image.
Now where this scaler shines is with my HD sources. On Sat TV HD channels the image really looked better. Not a vast improvement but the image looked sharper and cleaner and the scroll on the bottom of news channels was far easier to read. I would compare the PQ to that of my plasma TV with how sharp and clear the image is as before. Would this scaler be worth the advertised cost of 2,000 retail well no in fact if I spent 2,000 I would expect all inputs to look fantastic and that wasn't the case but with the improvement on HD it was well worth the 150.00 I did pay for this unit. Now I have not tested any of the HDMI scaling or the 1080p which I understand are fantastic on this scaler by since my older RPTV only does 1080i and component inputs I stuck with component on all the inputs. This scaler has HDMI 1.1 inputs but since I didn't want to bother with HDMC issues with inputting HDMI and outputting component I just stuck with component. All audio was just put through my receiver and never put in the scaler as HDMI 1.1 won't pass DT'S-HD, Master,DD+ or lossless audio so no since in using that besides my receiver has audio sync which would be the only reason to hook audio up to this scaler.
My main reason buying this was to control the overscan issue that comes with all RPTV. I previously had gone into the service menu on my Pioneer Elite and reduced overscan from 8% to 4% but even at 4% it would still cut off half the ticker at the bottom of news and sports programs. The DVDO has something called "under scan" which reduces the image. You can first put on a geography screen and leave it on which shows you the lines on all four corners and mid border lines and then you adjust under scan till those lines are on the very edge of your display. You can also adjust horizontal and vertical shift of the entire image to make sure everything is centered. This was a helpful tool as my Directv box even when "centered" was applied on the Directv setup was off kilter horizontally by about 5% on my TV. After adjusting to get perfect centering and adjusting the horizontal and vertical image I then applied under scan and wow what a difference. Now the entire Sat image is displayed and because the image was essentially shrunk it sharpened up the image even more giving more of a new flat screen image quality which I really liked.
I have my Directv, Sony Bluray and Toshiba HD-DVD player going through my receiver and then output via component to the DVDO component 1 input while my Oppo DVD player is input directly to Component 2 on the scaler. What was strange is each input has to be saved individually and so you have to set up and save each input to maximize the PQ. When testing out the Oppo I noticed that the displayed image left a blank gap if you will at the top and bottom of the screen so I had to use the zoom feature up two notches to fill the screen. If I used Overscan to fill the image you lose what is called 1:1 pixel matching and this is what makes the scaler so great so by using the zoom it will cut off about 2% of the image on the sides but its so slight I can live with that. Besides I rarely watch regular DVD's anyhow so it wasn't that big a deal.
Overall I am glad I got this this scaler. The Pioneer RPTV already have great built in scalers but have no overscan features so this outboard scaler did a better job of scaling and of course no overscan issues anymore WooHoo. I am positive that if I was using this on a 1080p display with HDMI I'd want a VP-50 or higher scaler as those do a far better job of deinterlacing 1080i sources but since I am stuck on 1080i and component this VP-30 was a wise investment and well worth the 150.00 (also considering the seller was very honest explaining that was in mint mint condition and barely used and made the transaction very enjoyable). I'm seeing VP-50's going online for about 250.00 - 400.00 for those who want to take their cable or Sat to the next level it might be a fairly inexpensive upgrade to look at this, it did a great job on my older TV.
