I have VIP server.  I having same problem too.  It’s only happening after, upgrade too new version of UNI.   I spend more than one month with TMD.  They couldn’t fix this problem. TMD don’t have any idea about this. Waste of time with TMD.  I reinstall fresh copy of 10.1 in new folder.  That the solution for now.  The video uploading good. And, don’t upgrade until find the  new solution.  Anyone know how to fix, please let me know.
thank you guys
