I'm pretty new to this, putting together the shopping list for my home theater at this point. I was going to get the Oppo Blu-Ray Player, but one of its big attractions seems to be how well it upconverts DVDs.

Shouldn't the display itself be doing the processing? I mean it seems pointless to pay extra for a Blu-Ray just because it upconverts well, if the display itself upconverts equally well. And then the receivers all seem to want to do the upconverting, too.

Which device should be doing the upconverting? My display will be a JVC DLA-RS10 projector. If it doesn't do a good job at upconverting, I suppose I will look for a receiver that does.

It depends on what you define as "upconverts". There are different stages such as deinterlacing and then resolution interpolation i.e. upscaling the resolution. Deinterlacing is arguably one of the most difficult stages to get right most of the time. It's also not just about having a specific processor but also how it's implemented. For example the VXP in certain models of JVC PJ's performs relatively poorly with SD DVD compared to other products that use the same processor.

Best advice is try both and determine what provides the best result for you. There is some objective test material that shows the deinterlacing performance under known conditions that may help. If you do try the test material I would suggest using a mix and not just material that a processor manufacturer designed to show how well their processor performs. There can also be differences in the resolution scaling that may exaggerate artefacts that look similar to halos/ringing that attempt to create the illusion of a sharper image. Again this can vary based on what product is being used.

The Oppo BDP-83 has a " VRS by Anchor bay" chipset for upscaling , its the same tech used in the DVDO edge external scaler , it is highly unlikely that your TV or display has a scaler anywhere near as good.

On most receivers "upconverting" means taking analog signals and outputting them on HDMI or a higher quality connection , there isnt necessarily any scaling involved , whereas "Upscaling" means trying to improve the picture or audio signal by interpolation.

The vast majority of TV's and displays have very average scalers.

Other thing to remember is if you want to improve your TV PQ from say Sky STB as well as from dvd's then you can't use the Oppo Blu Ray (no HDMI input).
Use of the chip the Oppo uses is then restricted to some high end Yamaha AV's or the EDGE as previously mentioned.

It really depends on the display as some use decent processor. IIRC the RS10 uses a IDT Reon but I don't know how well it is implemented.

The ABT2010 is a decent enough processor but IMO it's let down by the resolution interpolation algorithm ABT use for "upscaling" DVD etc due to halo type artefacts. I use an Oppo 83 and and have DVDO VP but don't use either to scale DVD due to this. Also auto cadence on PAL material can be a little hit and miss which again may be bettered by some displays or AVR's. The implementation of the ABT2010 in the Oppo 83 is different to the DVDO Edge which has limited manual cadence options. This means your may still end up with artfacts with some DVD material.
