Exactly, the mp4 the PC users here use, is not standard h264 encodes.

The guide I wrote, and the software Zarxrax coded create perfectly standard H.264 encodes. In fact if you use x264 and MP4, it's still perfectly standard.
Perfectly standard, just too complex for iPods and stuff to play due to their low CPU power. A H.264 encode would only be non standard if you stored it in AVI, MKV or OGM, since MPEG only specify MPEG-2 Transport steams and MP4 files. You may also be able to store it in MPEG program streams (MPG), but it's not common and not recommended.
Just because a certain hardware device does not play it, does not mean there is a problem with the file, for example I can create a perfectly standard file that won't play in quicktime because quicktime only has a partial decoder; which is Apple's fault, not mine or anyone elses.
Unlike MPEG-1 which was regularly used for 352x240/288 encodes at 1.15mbps, H.264 scales from resolutions as small as mobile phones (128x96) up to studio quality at 4096x4096, so of course you can't expect to play a certain encode on anything.

Now, why the difference? It can't be processing power, cuz then the first two wouldn't work in any player. Am I correct in thinking that?
