[packman] Various packages got downgraded?!?

[Smartysmart34]

Hi all,

while investigating my vlc2.0-upgrade-issues i just realised that some
major packages (libxine & Gstreamer) were installed in a specific
version and are NOW only availlable in lower versions. e.g.

libxine1-codecs:
installed: 1.1.20.1-60.2
available:1.1.20.1-58.12

gstreamer (various)
installed:0.10.36-72.1
available:0.10.36-65.1

My system just refused to Auto-downgrade. So what's going on here?

Cheers,
Martin
