any blue ray player is not a good source, there is your issue, also downscaling does not result in jagged edges, up scaling does.
You are coming back to numbers on paper, not to quality.
I will put my up scaling DVD player up against most Blu-ray/HD-DVD players.

Jagged edges are caused by the distance in the pixels (dot pitch) being very high, this is why even the best 480p inputs look like crap stretched out over 42"
All the upscaling DVD players do is use algorithms to try and figure out what goes in between the pixels that the source cannot provide in order to provide a picture that is almost 1080p (similar to anti-alaising). Which is what your tv does anyways. I cannot, like a CRT, change the native resolution, so it must upscale everything to that native resolution. A true 1080p source has information from the input about what should go in those extra pixels, and doesn’t need to calculate what should go in between based on an imperfect algorithm, thus creating a better quality (given the program was recorded in 1080p and not just upscaled and sold as “1080p”).
