I found that it's better to let the DVD player upconvert to 1080i and feed that to the TV than letting the TV do the complete upconvert. On the other hand, my Motorola DVR does a worse job with SD (480i) than the TV, so I have the output from the DVR feed in whatever it is originally (480i for standard definition and 1080i for high definition).
The Denon accepts the inputs from your various components and upconverts to 1080p. It probably does a better job than the TV. If you feed a 1080p signal to the TV, the TV doesn't have to do anything.
So the sales guy was correct. You have to decide how you want to set things up. There are pros and cons to every setup. I do not have an upconverting receiver, so maybe someone can point out the pros and cons of that setup.
That's part of the problem with this whole upconvert to 1080i thing, I think you meant to say 1080i, not 1080p right? I'm not aware of anything that upconverts to 1080p... I don't think it's even physically possible. Upconversion is why I bought a AV amp with the Faroudja chip. They are found on the higher end stuff but your typical upconverter from a $80 DVD player is probably some who knows what... It does make a difference.
I don't know what Samsung uses for 1080i upconversion, maybe someone else does. From what I've read, often times the component will upconvert better than most TVs, though I don't know if this is true with these high end DLPs we're using. In my case... everything video goes through and is processed by my JVC 702B AV amp. They go to great lengths to point this out in their advertising for this amp that it has "DCDi by Faroudja" and for good reason.
Another small item... You might have noticed, as I did with Charter Cable... that if you pipe their non HD signal into it into one of these TVs it is terrible. That's because, the first 99 channels are analog, not digital... for compatibility with older sets. Even though you have "Charter Digital"... which I think is very misleading. This wont' change till 2009. The 480 digital ain't bad and the HD looks very good. What you may be seeing if you have a lousy picture when watching 480i stuff, it's probably because it has to do the A to D conversion, which from what I've read doesn't work very well on a lot of equipment.
