Can't mvpmc detect the type of data it is receiving from the stream itself? I thought mpeg files carry such identifiers (or avi for that matter). If so, then mvpmc could stop reading the stream, and switch to the vlc mechanism. jan > Ideally, I wish there was a way for the MythTV backend to identify > the capabilities of it's clients and act accordingly.
