Let's get the facts straight:
1. This player will not upscale through component outputs because that's an analog, unencrypted connection. Samsung is a member of the DVD forum and as such, cannot output an upscaled signal through any analog, unencrypted output.
2. This player will probably not work well, if at all, with a non-hdcp compliant monitor through the dvi connection because it IS an hdcp-compliant player.
3. If you have an hdcp-compliant set, this player WILL in fact upscale your dvds to a 720p, 768p, or 1080i resolution.
All of this aside, the HD-841 isn't a good buy anyway because it has the picture quality issues associated with the first upscaling dvd player from samsung, the HD-931.
