[QUOTE="mm1352000, post: 1118949, member: 82144"] Ahhh. This is unexpected, unintended and not really desirable from TV library's (my) perspective. :( TV library doesn't intend for the filter to try to receive the stream until the graph is started. From TV library's perspective, IMediaControl (graph control) is used for stream start, stop and pause; IFileSourceFilter is only used to provide the URL (tuning parameters). Unless the graph is running when Load() is called, the library doesn't expect the filter to do anything except record/cache the parameters and [I]prepare[/I] to connect/stream. One reason for this expectation is that tuning can be cancelled. It is possible that Load() could be called without IMediaControl.Run() (due to tune cancellation from the user), and it is expected that the filter should have no problem with that. It is also expected that IMediaControl.Run() + Stop() + Run() might be called without Load(). The filter would just use the existing URL, and control the connection/streaming as required. Okay. Such an error would be completely unexpected, because TV library didn't intend for the filter to try to open any connection or receive data. Only parse the URL and apply the required configuration. Seems like the filter implementation is currently incompatible with TV library. :( [/QUOTE]
