Change a recordings file name

[alon24]

Hi,

I have a recording say "house - who am i".
the filename it was recorded in was "sageXXX-2.mpg"

I would like to change that filename.
I am using the sagex.api classes, and I have a refrerence to the mediafile after searching for all tv shows and filtering by show title.

Now what? how do I change the file name in the db?
Tried this:

public static void main(String[] args)
    {
        Object files[] = MediaFileAPI.GetMediaFiles("T");
        if (files == null)
            return;

        for (int i = 0; i < files.length; i++)
        {
            RemoteObjectRef mf = (RemoteObjectRef) files[i];
            String title = MediaFileAPI.GetMediaTitle(mf);
            if (title.indexOf("house") > -1)
            {
                Object airingMF = AiringAPI.GetMediaFileForAiring(mf);
                File[] segFiles = MediaFileAPI.GetSegmentFiles(mf);
                
                for (int j = 0; j < segFiles.length; j++)
                {
                    File file = segFiles[j];
                    System.out.println("\tSegment files: "
                            + file.getAbsolutePath());
                    System.out.println("\tpath files: "
                            + file.getParent());
                    File newFile = new File(file.getParent() + file.separator + "black21.mpg");
                    file.renameTo(newFile);
                    Object mf1 = MediaFileAPI.AddMediaFile(newFile, "");
                    MediaFileAPI.SetMediaFileShow(mf1, mf);
                    MediaFileAPI.SetMediaFileAiring(mf1, mf);
                }
            }
        }
    }

but it just adds to the files for the show and does not replace it.

Please help.
