I am going to convert a bunch of my AVCHD (*.mts) videos to H.264 (*.mp4). Videos was taken by Canon Legria HF200 (Pal version of Canon Vixia HF 200) in 1920x1080 XMP. I have Adobe Media Encoder CS4 and prefer to use it.
I have a simple question! Which of setting below is better?
a) 720 x 405 : Pixel aspect ratio = Square pixels or
b) 720 x 576 : Pixel aspect ratio = Widescreen 16:9
Ps. 2nd option is a Adobe Media Encoder preset for PAL DV Widescreen High Quality!

It depends what you are going to do with it. Square pixels might be best for portable devices or flash playback.
Many players (hardware and software) will not respect PAR/DAR flags. If you want to be sure people will see the correct AR you should use square pixels. And you can't use a 405 pixel high image with h.264 encoding. It has to be mod4, at least. So use 400 or 404.
1920x1080 is better!
(no one uses 720x405)
then maybe 852x480
then maybe 704x396
then all the way down to 640x360
or even 512x288
Take your pick! and make sure it plays in the target device(s).
High quality double-rate deinterlacing is strongly recommended (assuming the source is interlaced).

Thank you David. I will consider the common file resolutions.
I think 704x396 is the best common file resolution for converting a 1920x1080 file to a non HD video format.
