The only thing that the plugin can do is to control that all files are present when it builds the playlist... And what to do then ???
I think that that is all you need really,
(1) Read filepath(s) from a field in ant database (allow user to choose which field it checks)
(2) Check if these files exist, if not prompt user to abort, retry or ignore (if they ignore, don't add to playlist)
(3) Pass the playlist to g_player
Like HappyTalk said, 99% of the time the multi-part files are located in the same place. Most are on the same DVD at least, if not it's really up to the user to sort their file structure out.
Also, I think if you released your source code we could help. At the very least we could see what limitations the plugin has, and stop bugging you about features that can't be done
