HDC, RE: "Pentium III 700 Mhz Coppermine Chip using 128 Mbit 100Mhz SDRAM and a 32Meg video card."
The speed of the CPU would have the most effect on the number of frames per second processed, resulting in greater "smoothness" of motion, or less jerkiness in the movements. However...
RE: "Windows Media...Unfortunately, it was only a little better (ie. less blocky) than my current Presario Model w/ 200Mhz Pentium I w/65 Mbit 66 Mhz SDRAM using a cable modem."
However, the blockiness is more directly related to the quality (long story) and number of bits-per-second used to encode the image (i.e. encoding makes a difference). If the image were encoded for a bit-rate of 80kbps, then even if you had a cable modem, T1 line, or OC512, your system just wouldn't work any better. (Sorry).
The blockiness is caused by a truncation in the number of arithmetic coefficients used to represent 8x8 pixel patches of the picture (I don't think you really want to know the details).
Since you need data rates of 400-500kps to produce VHS-quality video (i.e. pretty darn good TV-quality), a DSL line should be pretty close to VHS-quality. [ Now, do you know why Intel wants either DSL or cable to take off? It's like TV. ] However, most of the Public Internet is 40-80kbps, which will remain blocky, even if you have a 1 GH Pentium and 1 GB of RAM. [ Now do you see Intel's dilemma? ]
RE: "I've been waiting to upgrade until the picture has little or no "blockiness" on full screen. What needs to be developed for the image "blockiness" to be eliminated or greatly reduced?
Will the new Rambus memory do it?
Does the video card need to be higher than 32Meg?
Does the PC need an even bigger BUS?
Since I use a cable modem, I believe I have enough bandwidth."
But what rate is the source sending it out at?
