Hello. Parole does play most of the files, but I sometimes get messages asking me to install additional software (MPEG-2 demuxer, or RIFF/CDXA (VCD). The message says it can be installed automatically. Yet when you click "install", nothing happens. Why is it that this demuxer does feature in the plugins?
Let's handle this problem in bug #14529. *** This bug has been marked as a duplicate of bug 14529 ***
