any SweetSpot video processor users???

I'm curious if this will work nearly lag-free for bringing in an RGBS signal into DScaler, with the windows desktop rotated so that the video overlay in DScaler is rotated...

I had a sweetspot card for a few years - works fine. If you want zero lag rotation (pivot mode) you need a graphics card with a 128bit (or larger) bus connection. The (3D) speed itself is not important.

thanks for the info, I didn't realize it would depend on the graphic's cards bus speed, but that makes sense. As a test I hooked up an old hauppauge wintv card and its composite input seems to work without any noticeable lag on the video card (gts 8800).

Did you have to readjust any video position/scale settings per game if you were using the RGB+sync input?? I noticed at least with the composite video, games with different horizontal syncs require different adjustments in DScaler to get the whole picture on screen (Raiden compared to viper phase 1 for example). It makes sense though since even on an RGB monitor they position the image differently... I don't mind having to change settings, but it is a little cumbersome to navigate with the windows display rotated.

I'm thinking about maybe putting together a PC from space parts for playing media on and allowing input of old game systems + arcade stuff, with its output hooked up to my projector, so it would be nice to have it rotate the image when needed without having to move the projector and refocus everything...

without any noticeable lag on the video card (gts 8800).

The GTS8800 is fast enough, no problem. it's just that in Pivot mode oftentimes the hardware acceleration is dropped and with 64bit onboard cards I've noticed delays and/or dropped frames. Horizontal gaming with onboard graphics are fine though.

Did you have to readjust any video position/scale settings per game if you were using the RGB+sync input??

you probably have to, yes. I haven't tried any PCBs though, so I can't comment. I also stopped using DScaler, since there are better alternatives (e.g. iuVCS).

Is there any known solution to grab 240p @ 60hz with the Sweetspot? We grab our game footage with it and need always to drop all odd or even screens with DScaler. Especially flicker FX is a problem as it either is completely missing or is always shown...

I've done it a few years back. You just have to run the captured AVI through a frameserver with the appropiate processing. I succeeded doing this in Virtual Dub and AVISynth - just choose what you prefer. I don't think that I have kept my scripts somewhere, but if you upload me a minute of captured 240p60 content (HuffYUV please), then I should be able to work it out again within no time.

EDIT: you know what a frameserver is ? It's a live processing software which creates a 0-byte reference AVI file from the original source. This way you can apply all the filtering you like without the need to run more than the final encode.
