What Happened 2 My PSP??!!!!

Last night I downloaded the Core Media Player from corecoded.com & saved 2 videos from youtube using the internet explorer on my PSP.When I went back 2 make sure the video player & the videos downloaded-I couldnt find them anywhere.I stayed up till like 3 in the morning screwing around trying 2 figure out what happened 2 them but I cant find anything.I know they downloaded or there on my PSP somewhere cauz a big chunk of my memory is gone.Does anybody know what I did wrong?Where & How do I get my player & videos or at least erase everything & get my memory back?Thanx

ok they might be in hidden folders so go to your root of your memory stick again and then at the top of the window click tools>folder options>view and then check the "show hidden files and folders" if u still cant see it back up wat you want to keep on your memory stick to your computer and then on your psp go to settings>systems settings>format memory stick this will delete everything that is on your memory card hope this helps and for the future if u want to watch youtube videos use this itz called psptube

Are there any video players out there that will play any internet videos on my PSP?
A player that also wont take up much space

ace: Please don't double post, this is your last warning.

This is probably a stupid question but......How do I get 2 the root of my memory card? Whats a double post?

when you stick your memory card into your computer and you click open folder to view files or when u plug in the usb cable and you open folder to view files that is your ROOT folder it will have your PSP folder MP_ROOT volder and others but those are the main folders you should see.

I dont have a 5 pin USB cable at the moment.Is there a part of the computer I can just put the memory stick into or do I need a USB cable before I can do anything?

well i told you the only 2 waysXD there is 1 more either you stick your memory stick into your computer directly or with a usb memory card reader if u have a camera u should have a 5pin usb cable
