@Abcdefmonkey That is the wget logfile that is used to follow the download progress of the video file. The script could be trying to delete it while it's still in use. Try this edit and see if that issue is fixed. http://paste.kde.org/183302/raw/

@Fuzionx I'm glad it's working for you now.
The last dialog is not scripted to close but you can add that line if you want it that way.
Just add a line under this one:

dcheck did -a %dname 11 Conversion Complete in $duration($calc($ctime - %start))

I have this at line 35.
Just add this line under it:

dcheck dialog -x %dname

Thanks for your time and patience Abcdefmonkey & Fuzionx .
I really appreciate it :)
