>hey anyone know what the deal with alignment is?
Can be different for each set and manufacturer. They did set them after a signal generator in the factory, either by hand or automatically.

>it seems to be different for each console i have
The (chip) engineers/designers (4th gen) or game programmers (5th gen) often made it simple and set the center and size after the sets they had. In the 6th console gen they might used advice (BT.601 standard) how to handle this properly.

>my original xbox is always perfect.
Because it might complies with the BT.601 standard.
GC and Wii does as they have a 13.5mhz or 27mhz crystal like many DVD players, DVB receivers or TVs with digital processing.

I personally set the geometry of my (SCART) TV sets after that what i have and use.
The horizontal size and center after the composite of the PAL NES (i use SMB1 and cutoff 1-2 pixels of each side of total 252 to hide border artifacts, also only non-RGB device i own) and the vertical center roughly after BT.601 (my TVs displaces 50hz and 60hz from each other by 5 interlaced lines) and the size to get the correct aspect ratio (a circle generated with a square pixel clock).
I use a external SCART RGB shifter to set the horizontal center of RGB sources myself independent from the TV.

My PAL NES is a little shifted up with the "correct" vertical center setting of the BT.601 standard. Just like any other common capture device that complies with it.

0x05 to register 0x09 on the SAA7113, Aperture factor = 0.25 .
Also i forgot to mention that the chrominance bandwidth limit was set to 620Khz (like VHS), i raised it to 1000khz.
