Hi, Being a regular lurker on these forums, I thought I would give to the community for a change . I recently became the proud owner of a Crystalio video processor after upgrading from an HTPC with H3D card. I have found it much more convenient to use, and it has better picture quality even on my plasma screen (dont laugh). I thought I would share some of the settings I have been experimenting with, and some of my experiences with the unit. My goal was to get the display into its native or (as Pioneer calls it) dot by dot mode. The PDA 5002 card is usually pretty co-operative in this respect, but the 503mxe does suffer from tearing issues when using a vertical refresh rate of 60Hz. This is a known issue thats been commented on before in the plasma forum; it is particularly visible in films like the PAL version of Blade (the rave scene), and in Sleepy Hollow. I initially started by setting the output source to DVI, and the input source to component (my DVD does not have SDI out). I then set the display configuration to closest matching resolution (using the resolution menu, not the output configuration menu turns out this for analogue displays like CRTs). Luckily, Crystalio has a built in configuration for a display of 1280x768 at 60Hz, which saved having to work out the actual timings for front porch, back porch etc. As expected, using this configuration produced tearing on both PAL and NTSC films. I then used the edit resolution feature to adjust the vertical refresh rate. Moving it to 70 Hz cleaned up the tearing in both PAL and NTSC, I also tried 72 Hz but found this was no better (for NTSC). I then tried to get to 50 Hz and 75 Hz (supposedly good spots for PAL, being multiples of 25 instead of 24 for films mastered for NTSC), but could not get a lock (both frequencies are outside the specification for dot by dot according to the manual I have so is 72 Hz BTW, but it seems to get there). So it would appear that 70 Hz is the sweet spot for the 503, as has been suggested on other AV forums. Running at this frequency does have some judder, but the Crystalio seems to handle this better than the H3D did the ticker-tape on CNN, for example seems much smoother (but still not the glide effect you get on a CRT based TV). Using the Digital Video Essentials DVD I then set up some of the other display parameters, such as aspect ratio (native mode has an actual aspect ration of 1.66 not 16:9s 1.78). These changes all went well. Although the LCD panel did get corrupted on a couple of occasions (this was firmware version 3.0.2). As PMS are actively updating the firmware, I was not too worried by this. I am also happy to report that the Crystalio worked perfectly with a device using SCART to output RGB (my NTL set-top box), I have always had to jump through hoops to get this to work with other products (thanks to the low synch voltage due to using the composite output for synch), but a SCART to RGB (with sync on composite) cable has worked fine no glitches or loss of synch. I just needed to change one of the component inputs to the Crystalio to RGBS easy! The only down-sides I have hit with this product (so far); have been with the stability of the firmware which is still a little flaky, but this only effects initial setup (when using the LCD panel and buttons). I was also surprised to find the fan noise was not much better than my (admittedly quietened) HTPC, but you dont notice it once a film has started. So, I would count myself a satisfied customer.
