Generally ok. nitpicks...

under "Sample Aspect Ratio":
You've already said that it may be called "Pixel Aspect Ratio", so don't 
then use PAR to mean something else. Change "Picture Aspect Ratio" to 
"Display Aspect Ratio".

under "Overscan":
I'd put a stronger statement against using it. Overscan is useful only if 
you're encoding for a device that can't display the whole frame.
If the decoder/hardware is capable of displaying the whole frame, cropping 
off the borders is always better than leaving them black.
SAR has nothing to do with overscan, unless you mean crop and scale to 
mod16, in which case you should say so.

under "Full Range":
-   Yes, but there are only few decoders that support it.
+   Yes, but there are only few decoders that distinguish between the two.
