How did you transfer it from you desktop to the sdcard? My sdcard is formatted in FAT32, which can only transfer a max of 4 gigs. The unzipped file size is 4.88 gigs. Too large for FAT32 to accept. So I formatted to ext3 and then everything got interesting. I wrote my sdcard to /mnt/sdcard/ and it totally messed up my camera and gallery. So in short I am giving up for now, may try again at a later time.
