Noticed Upmixing Audio feature get stuck even though time remaining part shows it's ticking. One video got stuck at %.05 and and time went up to 186 hours. From AAC 2.0 to EACS 5.1. Tried different videos and the results are the same. I tried the Upmixer alone and it got stuck too. I upgraded to 2007 and same result. I'm not sure if i did something wrong.
