Getting full screen 480 x 272 AVC MP4 files to work on my PSP

For some reason, I thought it used to work, but maybe it never did. I have the ImToo MPEG Encoder version 3, and it comes with the PSP Video Manager which was the problem. I thought it was the encoding that was causing it to say "unsupported data", but the encoding was fine all along. The PSP Video Manager (That comes with ImToo) was putting them in the G:\MP_ROOT\100MNV01 but my PSP did not recognize them. I had the firmware 3.30+ that supported 480 x 272 AVC MP4 files, but it just didn't work. It had the correct naming schemes M4V00001.MP4. Putting the encoded files directly into the G:\VIDEO folder worked perfectly. The .THM files that the ImToo generates should be renamed to .JPG.
One last note about ImToo, it is probably the best and easiest encoder out there. I've used things like:
3gp encoder
Dr Divx (and the many generations of it before that)
And the common problem is that virtualdub won't support mpegs, tmpegenc won't do avi, nothing will do mov, 3gp encoder won't do xvid (I think) and the list goes on and on. First, it takes you a good few hours to figure out the quirks and gotchas of each encoder, things like how some numbers have to be divisible by 4 or 16, or that it doesn't support mpegs, or you need to raise the bitrate because the encoder only supports 1-pass. You need to make sure the aspect ratio of what you encode will be what you want. Isn't there a drag and drop program that just takes any format, and spits it out in any format, and doesn't crash? yep. ImToo. It rocks. Nuff said.
