With the arrival of Firmware ver 1.2 for the iPod, the iPod could not play videofiles with greater resolution and greater bitrates.

What I want to know is:
Using the presets for 5.0 and 5.5 in, say, meGUI and the same resolution and bitrate, will the two files be the exact same?

Like say a 5 minute music video using 320x240 and 400 kbps? Exact same, no difference at all? Or is one of the profiles better for certain files (say, files with a resolution 320x240 or below) and one for another or is 5.5 superior to 5.0 in every way?

I just want to know so that I'll know if I should use 5.0 as long as the resolution is 76800 pixels or below or if I should always go for 5.5 or whether or not it doesn't matter at all as long as I use 5.5 for anything with more than 76800 pixels.
