Try to either replace it or delete it before a fresh videocenter re-install.

These are the frequent place, where videocenter will leave behind files,

/home/user/MyDocs/.videos
/home/user/videocenter
/media/mmc1/videocenter

Or try this with root,
rm -fr /home/user/videocenter; this deletes all videocenter database.
rm -fr /media/mmc1/videocenter; this deletes myvideos database and all video files which are downloaded by the Video center from SD card

Does this help?
