Please give us a step by step, I have never understood the ROT.


ROT stands for "Running Object Table" and it is well defined in the link below
http://msdn2.microsoft.com/en-us/library/ms787252.aspx

As I said before, you need to do those steps (from 8 and after) relatively fast or dvbdream will freeze so this is rough a solution but it should work
Here are the steps:
1- Menu options -> video -> Make sure “Reset DS after channel-change” is unchecked. This will avoid recreating the graph each channel change so changes to the graph that you make would remain. If you change between SD HD H.264 channels your changes will not remain as I believe it resets the graph.
2- Menu references -> General -> Make sure attach the graph to ROT is checked. -> click ok.
You might need to restart DVBdream if you change that option.
3- Restart DVBdream
4- Menu Tools -> Graphedit. It will open the Graphedit app. Or you can start it directly
5- Graphedit menu : File -> connect to Remote Graph. Select the IFilterGraph -> ok.
Now you should see the filer graph that is created and used by DVBDream.
6- Menu -> view Disable AutoArrange: this will make it easier to disconnect / connect filters faster.
7- Add your desired filters to the graph by using: Menu Graph -> Insert Filters
8- Now to the critical phase: pause the graph
9- Stop the graph
10- Disconnect the filters and reconnect the new ones.
11- Run the graph.
12- If all is ok, you can go back to using dvbdream

Small example of what can be done with this change:

With this kind of changes possible, I believe that you can change filters, audio and video renderers, maybe output video to hardware decoders etc…

Of course I do not think that DVBdream was not designed to work with such changes so please note that a lot of changes you might make to the graph will cause crashes in DVBDream.

Hope this helps.

I tested the second method (customized ffdshow).

The SD channels work perfect. However...

It causes problem to the H.264 channels. Now everytime when change to a HD h.264 channel, DD crashed. Even change codec back to Intervideo one. Anyone know how to deal with this, please....

What codec do you have selected for H.264?

Make sure under FFDshow video configuration that you uncheck H.264, so that FFDshow can't be selected by the directshow engine by mistake.

One more thing,

Does d3xt3rlab's FFDSHOW supports H.264? I cannot find it in h.264 codec list in DD, but after read the DVBN's post, I feel it does support h.264.

Thanks again. And I'd say, this Closed Caption is terrific.

For FFDshow to be listed as a H.264 codec in DVBdream you would have to edit the guid file, but it has been reported to not work.

For me, the graph building engine (Software) that Rel has built in to DVBdream, will select filters based on filter merit value, and what you select is not alway what you get. He does show you what codec's are in use, so a person can troubleshoot why a different filter is being used.
