I am having the same issue as pucker21. I get it after 89% is done. I am trying to write the dvd files from my hard drive. The log states Writing stopped: cannot obtain exclusive access. I am logged on as an administrator member. This happened on a 2nd DVD. Prior to that it said media write error but also at 89%. BTW, the link in Webslinger's post maybe damaged as it gives this message: No Thread specified. If you followed a valid link, please notify the administrator Thanks.
