been using xmm for a while now... realy like the integration with the Video Browser plugin and my suggestions are related to this topic:
1)in the mediacenterdir, instead of using links to the movie files, why not use a wvx file? that way, if we have a 2 cd movie, it will play the 2 files together. here is an example:
<ASX version = "3.0">
<Title>300</Title>
<Entry>
<Ref href="G:\Filmes\300\300 - CD1.avi"/>
</Entry>
<Entry>
<Ref href="G:\Filmes\300\300 - CD2.avi"/>
</Entry>
</scriptSX>
that way we don't need to choose to play cd1, then play cd2...
2) remove the movieID from the directory name in the mediacenterdir. it just looks bad :P
3) enable us to export our series to media center ( on this, use the videobrowser series.xml and tree structure) ( take a look at this app: TVscout -> http://www.codeplex.com/TVScout )
4) Option to choose directory where we keep the mediacenter dir, and another to copy the info into the movie folder.
