[QUOTE="CyberSimian, post: 1287036, member: 141969"] I [i]think[/i] that when playback of a video stream is requested by the user, the system (MP or Windows or ...) creates a "graph" of different processors that specifies how the data is to be processed. It starts with the composite data stream which must be split into audio, video, subtitles, and (maybe) other stuff. So visually it looks like a flow diagram. (I don't understand why the term "graph" is used for this.) Scanning for and detecting channels does not involve a "graph", so that would still work OK. It is when you try to play live TV, or watch recorded TV or other video that the graph problem would arise. I think that the graph indicates which codecs are to be used for each component of the data. So a problem with one or more codecs on your system could result in MP being unable to create a complete graph. The codec problem could be because a required codec has been deleted, or removed from the list of available codecs, or the default codec has been changed, or something else. There is some way of viewing a list of codecs, and changing which codecs are the default ones, but I don't know how to do that (I suspect that it is a command with a horribly-obscure syntax consisting of strings of hexadecimal numbers). :( -- from CyberSimian in the UK [/QUOTE]
