Wont recognize memory stick

You need to create folders on your PSP memory stick. For example, downloaded games need to be in a folder called ISO, music needs to be in MUSIC, video needs to be VIDEO etc etc.
Hope this helps

The file is not supposed to be opened by your PC. You have the transfer the file from your PC to the PSP. To do this, you need a USB cable and you have to plug your PSP into your PC.

Download procedure

1. Prepare to save the update data on either system storage or Memory Stick Micro™ (M2)™ media, using one of the following methods:
   • Connect the PSP® system to the PC using the USB cable
   • Connect a commercially available Memory Stick USB reader/writer to the PC
   • Use the Memory Stick slot on a PC
2. Create a folder for the update data on either system storage or Memory Stick™ media.
   
   Using your PC, create a folder named "PSP". Within the "PSP" folder, create a folder named "GAME". Within the "GAME" folder, create a folder named "UPDATE". (Folder names must be in all uppercase letters).
3. Download the update data for the PSP-N1000 (PSP®go) series and save it in the "UPDATE" folder created in step 2.

Notice
You must save the downloaded data as noted in these instructions. If you do not save in the correct location and with the filename shown below, the system will not recognize the update data.

• Location: Save in the "UPDATE" folder
• Filename: Save as filename "EBOOT.PBP"

it depends on your version of psp try upgrading to 5.03GEN-A

hi
is it just the one movie that wont play or have you tried music and game saves?
a few things to check
1 is the memory card showing magic gate supported
2 check if the card shows 15.?gb with nothing on it
3 try loading the card with 15gb of music and pictures

i bought a 16gb pro duo memory card from ebay that was a 4gb card showing in the psp as 15.4gb but corrupted every thing after 4gb.
if you also find that the card is only taking between 4-8gb of data contact ebay as this is likely a fake card.

press select button then when you see the CPU CLOCK XMB just turn it into 333/166 and also the CPU CLOCK GAME turn it into 333/166 and the UMD ISO MODE turn it into Sony NP9660 and then exit...

Reformat Your PSP.

I think That's the solution

first make sure your usb connection is working/active so that you can transfer your files seamlessly via usb cable (between psp and mp3 files).also,you can save all important psp files to your pc just to be safe,then try to format the memory stick using the format feature on your psp (go to system setting then click format memory stick).no guarantees,hope this works.
