For some reason, when I tried Dscaler 4.1.7 with Iomagic PVR Svideo input and SVHS JVC VCR outputting SDTV or VHS signals, it showed a 4 pixel square, green, flashing in and out in far left upper corner using "gradual noise filter" and all else to default settings. Weird as it was not there last time I used Dscaler 4.1.7 or older versions. I'm not using Powerstrip or any scaling software. Just running Radeon 7200 at XGA for my NEC LT150 DLP PJ using high quality SVGA cable into LT150 VGA input. DVD plays fine using all software players without any flashing "green pixel". Did not change any video drivers (still using Win98SE, nonCatalyst driver--7189, I think). Ideas? Should I down grade to an older Dscaler as it was not there before? Should I reinstall Dscaler to R/O corrupted files?
