Trouble reinstalling mplayer for use with PlayWMA in Squeeze

I recently had to do a factory restore of 4.2.19 of my Ultra 6, and I am almost finished with setting it all back up, but I am having problems installing mplayer through the command line. Mplayer is required by the "playWMA" plugin in squeezecenter because I have ripped my music collection to WMA and squeezeplay clients won't play WMAs natively without first transcoding them using "playWMA".

Under my previous config, I had no trouble installing mplayer with "apt-get install mplayer" after doing an "apt-get -f install" and "apt-get update". No such luck this time. I keep running into unmet dependencies that are "not going to be installed".

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

Since you only requested a single operation it is extremely likely that
the package is simply not installable and a bug report against
that package should be filed.
The following information may help to resolve the situation:

The only differences I have noticed between this install and previous is that 4.2.19 has apt installed by default--I did not (and could not) install it as an add-on, but it was already present when I tried the command line. Mplayer survived my Raidiator upgrades to 4.2.19 before I had to do the factory reset, so I know it is possible to get it working on there, I just don't know enough about packages and sources to get it working.

Can anyone help?

Thanks
