the PC may be able to create a 1080p output, but it is still reliant on the source media. So a DVD deinterlaced correctly and upscaled up the PC to 1080p will look truly phenomenal. However take exactly the same hardware/software but use a HD-DVD disc as the incoming material and the image is several times better. Not just because the material is natively 1080p (and hence does not require lossy upscaling) but also because there is far more information on the HD-DVD disc for your PC and display to use to draw the final image. You have obviously seen some bad HD demos to say your PC is better (which is not a surprise as many HD demos are 1080i to displays which cannot apply inverse telecine as discussed above). Regarding HD clips via PC and same HD via disc (BD or HDDVD) I have found very, very few HD movies available for download that can compare to their HD-DVD/Blu-Ray counterparts. Most are overly compressed and/or upscaled from the original SD master rather than truly HD.
To WifiSpy (although jdb has covered it):
ONLY 1080i that started life as 1080p can be put back to 1080p. There are some cases of different cadences, but mainly because so much 1080i material is recorded interlaced to begin with.
It's even worse for us over the pond. 2:2 cadence detection is far more difficult that 3:2, very few displays even have this for SD let alone HD!!! Basically we're all up shit creek over here, with the only paddle being dedicated video processing
