One slight drawback to the iScan VP30 video processor is that it uses a field interpolation function called "field scaling" to handle 1080i interlaced HDTV signals instead of performing true weave based 3:2 pulldown 1080i deinerlacing. While, field scaling is far better than the traditional bob method (which actually throws away resolution), it is not quite as as good as 2:3 reverse pulldown which fully assembles the two fields into one whole frame without interpolation. The upcoming iScan VP50 does perform 2:3 reverse pulldown on 1080i, and the difference will be noticeable on 1080p displays, but the VP30's field-scaling also does a very good job and can often fool the eye. In all fairness to the VP30, it does this better than most other video processing schemes I have seen employing similar methods. If you have a display that features built-in 1080i deinterlacing and wanted to use that for your 1080i feeds, you could always turn the VP30 to Pass-Through mode (which will be available soon as a free download on their website.)
Another drawback is that in it's current form, the VP30 lacks grayscale controls, which if implemented properly could actually give it the ability to shape gamma curves and improve the grayscale tracking performance, therefore enhancing the overall color accuracy of many displays. As stated earlier, the company has told me they will be adding this to both the VP30, and the upcoming VP50 in the near future, and since both products are field upgradeable and the update software is a free download from their website, this is not a pressing concern.
DVDO’s iScan VP30 overall is an impressive video processor, particularly for standard-definition sources like cable TV, Satellite TV and standard-definition DVD. It will scale up to the highest resolution we have today of 1080p for the new crop of high-resolution HDTVs and projectors. The DVDO can be particularly useful with front-projection systems that have a wide variety of video sources, as it helps keep to a minimum the amount of wires running to the projector from your equipment rack. It also has an extremely comprehensive feature package for set-up, several of which address some valid problems like lip sync issues and Y/C delay, and the connectivity options are as generous as it gets. At a list price of $1,999, the iScan VP30 compares very favorably with many high-end video processors costing two to three times its price.
