Probably other factors matter too - for example, cameras ;-))) BTW, if you want maximum quality you should not run mpeg2enc with default settings - increase -r (-r 24, -r 32) and set -4 -2 to 1 (-4 1 -2 1). Warning: these settings will make your encoding SLOW. Default settings is a compromise between speed & quality. Also it is possible to play with -N, -H and different quantization matrices: tmpgenc & kvcd matrices can give you significantly better compression (so you can decrease -q and get a better quality for the same file size). And CVS version provides better quality compared to 1.6.1 with the same settings (thanks to Steven to convince me :-).
