here is the psp videos basic format

368x208/29.97fps/768kbps Stereo/128kbps

how can i set that as the output file for a nero recode mp4?

i tried using an mp4 i converted...w/o the above setting and it's not recognized by the psp

i followed this
To copy video to your memory stick manually:

Navigate to your memory stick and open it, create a folder named "MP_ROOT" (if it doesn't exist) and in that folder create a directory named "100MNV01" (if it doesn't exist) - making the path to your video folder on your PSP X:\MP_ROOT\100MNV01 (X: being whatever your PSP's drive letter is, will usually be E. Copy the video file into the root of 100MNV01 folder.

Remember, you must leave the file names for the video from PSP Video 9 in their MV4XXXXX.mp4 format. You may change the number to whatever you like within the five (5) digits available, but you must not modify the scheme.
do i need a thm or thumbnail file also?

anyone?

i'm also using pspvideo and 3gp and they work fine. i just want another option if possible.
