Finally! after pissing around all day trying to get my crowd chants to play for more than a few seconds ive worked it out and here is a guide for all you loveley fellow players.
Right, before all this I found a pack of England League chants (mp3's) for all teams on this forum which a member put together (cant remember the name but thanx its awesome!) but when I imported them, they were just playing the first 2 or 3 seconds. Ive come to a conclusion that its the way they are encoded and the PS3 or Pro Evo doesnt like it so heres what I did:
Step 1: Burn your selected chants (mp3's) as an AUDIO CD not an mp3 cd (I used NERO).
Step2: Insert your audio CD into the PS3 and select "import" so it copies them to you PS3's HDD (this is the bit im thinking solves it as the PS3 encodes the files to a more playable way).
Step 3: Add your new copied/ripped chants into the "KONAMI_PES" playlist
Step 4: On pro evo in edit, go to team edit then "cheering stance" for your selected team then choose "MP3 library" and select the file/chant you want (note that the file name will now only be something like "AUDIO 1,2,3" etc as you ripped it from CD but you can change the name in the PS3 music section)
Now the chant plays all the way through and doesnt cut off at all! You can test it obviously by preesin SQUARE to prove it!
Hope this helps guys! Let me know if it does as ive spent ages!
