I will also suggest you to upgrade the BackgrounDRB version. May be  
1.0.1 .

Hi, It seams you are working on site similar to youtube. Kindly share  
your experience on following:

1. Where you store the files (database or file system)
2. How can we manage the storage if thousands of videos gets uploaded  
every day
3. Which player you are using to stream the video

Just trying to learn how youtube manages their traffic
