Thanks a lot Sharktooth. This will be a very good guide line for newbies.
BTW, just curious whether you would add more profiles for stand alone players or not?
Such as:
1. Nero Digital Certified Player. I'm not sure whether default settings will work on these players? If x264 works on these players, what's the possible settings for Max-Quality? Can High Profile in x264 be used?
2. Sony PSP (I think some information is available from bob0r's website
http://x264.nl/psp/)
Cheers.
