i posted this in the member chat b4 by mistake and moved it here.
this is a guide i wrote because some people dont understand how the video system on the psp works. the best converter for the psp is pspvideo9.com(freeware). i will now explain the psp video system.


the pspvideo9 converter inserts the msv tag needed for the psp to recgonize the video. the msv tag is sort of a secondary name for the video. when converted the videos file name is change to M4V10001 and the original name is aded to the msv tag. the m4v10001 file name is what the psp recognizes as the files format and how it is listed in the folder. once the psp regonizes the m4v filename it will then recgonize the msv tag and use it as the display name. with out a the proper file name M4V10001 and the msv tag the psp system will not recgonise it and will not display it. as long as the video has been converted to mp4 format and has the msv tag embeded in it the M4V10001 file name can be change manually when downloaded to the psp. there two diffrent filenames for the video depending on which audio format the video has been converted to. it will either be M4V10001 or MAQ10001.
the file name can be renamed like this M4V10001 -> M4V10002 ect. as long as its name includes M4V1****/MAQ1**** the last 4 digits can be any number from 0-9. where to save this file is in the mproot folder either the MNV one or the ANV folder
