After Installing Nero 7 you start frequently seeing COM Surrogate has encountered a problem and needs to close errors.
1.) Download and run the Direct Show Filter Manager from here
2.) Arrange the filters by company by clicking the Company column and scroll down to the filters by Nero AG
3.) Set all the filters that are not already red to 0x00200000 (double click the filter you wish to set, type 00200000 in the Filter merit textbox, click Set new merit, then close the dialog box. Repeat this for the other Nero AG codecs)
4.) Restart your computer
Update: Ahead has since updated Nero to version 184.108.40.206 which solves this issue. The update can be download from http://www.ahead.de
