DL-2 Stock Content Not Looping?

Well it's been awhile, which I guess is a good thing regarding any problems.:)

Anyone experienced any issues with the DL-2 not looping or "freezing up" of files in the middle of the clip with a majority of the stock content files?
Uploading custom or third party files are not a problem and those all seem to run fine.
The problem seems to be intermittent and can sometimes be resolved for a short time by re-booting the server, although it seems to be becoming more of a problem and occurring more often.
I briefly scanned the board and didn't see a thread addressing this issue.
Any suggestions or comments would be greatly appreciated.
