Yes, I'm very thorough with these types of tests. I make sure I know exactly what decoder, splitter, etc.. is being used at what stage. I also test other compression and different uncompressed fourcc versions in case the handling is slightly different. I use known colorbar and calibration videos (known YUV and RGB values). Avisynth's default conversion is a slightly "off" compared to other methods (this is known and discussed in other threads, possibly due to 8bt and rounding), but vdub's was way way off. It might be fixed by now
