This is a bit of a strange one - I have Girder st up to control PowerDVD, and when playing back a DVD, it works well. If I'm playing files from the hard drive via a playlist, when I press stop or next chapter for instance, the playback stutters slightly during the keypress, but the function isn't executed. So it seems to see the command, but more or less ignores it. Any ideas what this is and how to fix it? Cheers. Gary.
