MP4Box isn't a full-blown encoding program, it's just a muxer as far as I know/care. x264 itself and/or MeGUI are the programs used to do most H.264 encoding to MP4.
But thanks for the tips. It seems to me though, that, apparantly, ALOT of people just don't know how to encode mp4s than lol.
On a related note, I don't know why in the world so many MP4 releases lately seem to register as using HE-AAC when they really don't (if I remember correctly, CoreAAC seems to detect it although there isn't a frequency doubling, and I know dBPowerAMP's pop-up info in Explorer reads the files as High Efficiency, but MP4Box/YAMB clearly states that the file is Low Complexity - the weird part is, dBPowerAMP's pop-up info can correctly detect LC-AAC - my guess is that some weird process is being used on these files to make them report bad info).

Not to mention I see very little benefit for using HE-AAC for music - maybe if it's going to be streamed, but for archiving like most releases around here, I just don't see the point, considering it's meant for low bitrates and SBR or not, you can hear the difference between a 64kbps HE-AAC stream and a typical 128kbps LC-AAC stream, which is what the intended purpose of it is supposed to be - maybe because when properly encoded, HE-AAC streams have half the frequency of the source file it was encoded from whereas the LC-AAC stream retains everything with a matching bitrate to make it sound right; IMO, HE-AAC should only be used for audio streams that are predominantly speech, like with fansubs. The same especially goes for HE-AAC+PS, although as of yet I don't think I've come into contact with any of those.

Ok, never mind, it does detect a frequency doubling from 22050 to 44100 but after extraction through MP4Box it registers as a regular 44.1kHz LC stream.
