wmv tagged tracks coming up as untagged

[ScAtMaN]

I have a lot of albums in .wmv format that freebox cannot see the tags of.
In the config program they show up as Artist: No Tag Album: No Tag but they show up fine everywhere else, in WMP, Silverjuke, etc.  If I right click a track in explorer all the fields are filled in and present under the advanced summary and Tag and rename has no problem seeing them.
I read on here that someone had a problem with old v1 tags so I have tried using the sync tool in Tag and rename, with no change.  I have also used Tag and rename to download new tag information but that didn't cure it either, the config tool, after using the update library tool still cant read them.
I have the latest version of Media player installed with no plugins.

Just to repeat, this is only with those albums in WMV format.

Anyone have any suggestions, it's starting to drive me nuts now

Are they .wmv or .wma? If they are videos .wmv, you will need to use the betatag.exe in Freebox (non-mp3 tagger), but if they are songs, .wma, Freebox does not fully support .wma, and there have been issues in the past with .wma tags. What some have done is convert them to .mp3's.

Sorry, must have had some sort of brain fart!  I meant .wma

It would be a bit of a pain to convert them, there must be 70-80 albums affected but if that's my only fix.
