Does the Sony VPL-HS50/51 allow for switching between Standard Definition (SD) Colorspace , BT-601 , and High Definition (HD) colorspace , BT-709 ?
If it does not then one must be careful when calibrating this PJ . Sending a Test Pattern or Color Bars from a DVD (SD) through to the PJ will result in a 720p image with SD colors . Sending a "true" HD signal from a Satellite or Cable feed or HD-DVD (as in WMV-HD) will also result in a 720p image with SD colors .
If it does , then seperate calibrations would need to be done for the two different colorspaces , SD and HD and saved into different memories .
If the DVDO IScan-HD+ or the Accupel HDG-3000 are not changing the colorspace when they are scaling the image , then we are still only seeing SD colors and not all the benefits of having a HD PJ .
Someone in the Panny 700 thread mentioned having this option in the menus , but I can't locate it in the Operator's manual . Someone else mentioned here that they had spoken to a Sony Rep and that this might be a possibility in a future upgrade .
For those using HTPC's , try downloading this chart and see if you are getting SD or HD colors... http://www.belle-nuit.com/testchart.html
Just my 2 cents worth ,
