Movie sequences lag in Xbox backups...

[xxloganxx]

I am using generic (no name) brand of DVD-R media....although I don't think its because of the media. I realized that I had some uneccessary programs running in the background during the burning processes. I just backed up my Splinter Cell game today after realizing this and ended the tasks on the programs before burning. I put in the backup after it was finished and the opening sequence (movie) played flawlessly. Its amazing how sensitive the burning process is concidering I am running a pretty high end system.

Now I have to re-backup the other games I mentioned to try and prove my theory. Which brings up another question. I appologize if this question has been previously posted but, is it possible to backup a backup without having to network and copy files? If not, no big deal but it would be nice to be able to save some time that way.
