Newbie post, so pls be kind..... Have recently bought a CS2 scaler which I'm trying to set-up to feed my Pioneer PDP 503HDE plasma. Sources currently hooked up to the CS2 are: Sky+ box (via JS RGB-YUV converter) into YUV A & Tivo (via JS RGB-Svideo converter) into Svideo A (others to follow when I get some more BNC cables...). I'm outputting from the CS2 on RGB colourspace (the Pio doesn't like YUV) via the VGA output into the VGA input on the front of the Pio media box (the PC input). Am currently running the CS2 at an output of 'WXGA 60Hz' syncing on H/V (G/Y gives no picture); this resolution (1280x768) should match the native resolution of the 503HDE & (according to the Pio manual) 60Hz is the only frequency permitted for this resolution. Running this set-up through the PC input on the plasma, I get 3 picture shape choices (Full1, 4:3, Full2) - I'm using Full2 as this is the only one that gives me a stable 16:9 picture (Full1 defaults the resolution down to 1024x768 & gives nasty vertical banding on the picture). First thing... PQ is in general excellent. Tivo (even via Svideo) is amazingly clean & there is a definite improvement on Sky+, esp when watching the footy - less 'tizzing' round the edge of players. However, some definite concerns that I'm hoping someone can help out with: 1 Picture is 'jerky' - a big problem. On both Sky+ & Tivo, any movement (sideways & vertically) is stop-start. Particularly noticeable on the scrolling news tickertape on Sky News & when watching the ball moving across the screen on the footy, but evident to some extent on all content. 2 Can't 'snap in' the picture. Have read some of the posts in this forum & understand that the best PQ comes from snapping the scaler output directly onto the physical pixels of the plasma to eliminate scaling in the plasma as well. Have tried the test patterns on the CS2 (supplied in firmware 2.04) & whilst I can get the coarse pattern to work (e.g. Checker 8) the finer ones (Checker 1 & 2) show nasty rainbow effects. Have tried moving & stretching the picture horizontally & vertically via the CS2 menus, but no joy. Would be grateful if anyone has any advice - particularly re how to fix the stop-start picture issue. Am hoping to get Gordon down at some point to calibrate the system, but would like to have it a bit more watchable until then. Thanks, Simon PS Kinda related... has anyone got the Pronto friendly IR remote code for direct access to the PC Input on the 503HDE? Can't find it on the remotecentral website... & although there is a macro workaround, it's a pain.
