I can't seem to fast forward, skip titles, or use the commercial skip button when viewing recorded content off my hard drive (Panasonic DVD Recorder DMR-E85H). The buttons work fine when I'm viewing a DVD or editing content, but when I play video off the hard drive it just plays and I can't do anything. It plays the video fine, but it won't allow me to stop or do anything. The only thing I can do to exit the playing video is hitting the TV guide button.
