The 809 does a great job. You just want to avoid the video presets that do weird things to the color and stick with CUSTOM if you want upconversion and use DIRECT for sources you don't want scaled.
I also use DIRECT for anything I don't want touched (BD, PS3 games), but for anything else I watch (1080i HDTV and DVDs) I use THROUGH mode since all it does is upconvert to 1080p, CUSTOM mode leaves a a whole bunch of options that can be tweaked (although you could leave everything at off/default if you wanted to).
I haven't played around with the different noise reduction options available in the 809, I'm not sure how effective they are, historically noise reduction in upconverting/deinterlacing chips hasnt been very efficient in doing a good job of cleaning up the noise without significantly softening the picture. I would be interested to know what people here think about the noise reduction performance of the HQV chip in the 809, for SDTV/HDTV and DVDs.
Currently I just use through mode but I do pass my cable feed through an Algolith Mosquito before sending it to the 809 - still the best noise reduction option available today IMO.
