Hi!

I have a problem with EVR.

I create a graph to render h.264 stream. Microsoft DTV-DVD video decoder and EVR with two pins are used. Connecting decoder with EVR and closed captions through Line21 Decoder 2, the video renders. The I delete CC connection, start the grapgh and see nothing is rendered. Doing Stop and Start again fixes this problem.

The same behaviour is when I disconnect onlt the connection between Line21 decoder 2 and EVR.

Next I replace Line21 Decoder 2 with Cyberlink Line21 Decoder and everything works fine.

The question is what's wrong? I have my own AVC Decoder filter and it works the same way. On the second start, after cc is disconnected, the decoder hangs up on getting video delivery buffer from EVR. Symbols for EVR shows only that it waits for something.

How can I fix this?
