her teeth look sharpest in the nvdvd pic, but that could be because the brightness of that shot is set a little higher than tt1.5.
For me, windvd provides micro-stuttering, and nvdvd, tt1.5, do not. For me, windvd has problems with passthrough, nvdvd does not...(tt1.5 does). It has a lot to do with hardware/drivers which determine if a particular decoder exhibits these symptoms.
However, in my opinion the video quality of nvdvd and tt1.5 are the best.....powerdvd is downright awful.
I use a tt1.5 for video, and nvdvd for audio as it eliminates stuttering on my system. I will try platinum however just to see for myself if it's an improvement over windvd4
