LG Voyager VX-10000

lately the mobile youtube seems to have like every video that the real youtube does, right? much better than 2 months ago.i dont know why this happens but every video i uploaded on youtube, whether wirelessly from the phone(via. reg. vid message) or taking the card and putting it in my laptop and uploading that way the video on the mobile version is there, but when i play it the audio plays and the video is totally pixalated out,(works fine on the regular youtube version) why is this. does it not support 3gp? if it dosent thats somethin youtube has to step up on?
