Is there some trick to getting the progress indicators to work? I can see them, but there is never a bar there. The closest I see to documentation is this non-official site: http://www.instanttvchannel.com/roku/progbar , but that is presumably for their little app builder. Do I have to tell it to update? (I already set a "length" on the metadata)
The only other thing it does is it acts like PlayStart and sets the start of playback.
You still need to use the registry to store the playback time for your videos since metadata objects (like all objects) don't persist when your channel exits. When you create a metadata object, you should copy the saved playback time from the registry to BookmarkPosition.
