The DVDO iScan HD is a great de-interlacer and scaler and does more things than I guess I even really need. I also have the iScan ULTRA which I'll use instead. The HD probably makes the picture better in my situation, but I am in serious need of cash and since nobody is interested in my iScan Ultra, I'll have to sell the iScan HD. As far as condition, it has a mark on the end of it from being dropped by the previous owner, but its in perfect shape otherwise and works fine. Comes with original box, manual and remote and a couple of cables (A VGA to component cable and a serial cable). Clarifying the main differences between the Ultra and the HD. The iScan Ultra is a video processor with the SiL 504 de-interlacer (best one out there period). The Ultra takes video and de-interlaces it and in most cases line doubles to 480 progressive and outputs via a VGA or DVI cable. The Ultra has zoom and aspect ratio functions, digitla noise reduction and other features and acts as a video switcher with too component, too composite and two s-video inputs. For most regular widescreen projectors or displays of 856 x 484 resolution (16:9) the Ultra s is more than enough. The iScan HD is essentially similar to the iScan Ultra except that it has a scaler so you can output other than 480 p. You can output 540p, 720p, 1080i, 960p or even 1080p for instance. For projectors or other HD displays (plasma, LCD, CRT or DLP TV's) with 960 x 540 p or 1280 x 720p resolution or up to 1920 x 1080p, the HD can feed the proper resolution. The HD also has other features such as the lip synch feature, which matches the audio and video timing more precisely (there is an audio input and output on the HD). Also the HD can operate at frequencies other than 60 hz. Specifically for the iScan HD in terms of frequencies or "refresh rates"...... The iScan HD can be used at frequencies other than 60 hz. You can use it locked, or at different frequencies. I don't really know how all this works in terms of what works best for what, and I think I've left it as it was, but from the manual: Under the FRC settings (FRC = Frame Rate Conversion) For 50 hz input sources (I imagine 50 hz is mostly for PAL sources) , the available settings are: 50 L - source locked 50 hz 75 L - source locked 75 hz UNLK - unlocked For 60 hz input source (60hz is NTSC, thats for us here in North America, at least for me anyways), the available settings are: 48 L - source locked 48 hz 60 L - source locked 60 hz 72 L - source locked 72 hz UNLK - unlocked $850.00 CDN (or equivalent in USD) plus shipping, prefer local Southern Ontario or Greater Toronto Area sale.
