Closed Captioning

Summary:

I wan't to add Closed Captioning

Area:

My TV

Description:

I know MP doesn't support CC using analog cable/broadcast because all the developers are in Europe.
I also know some have had some luck using ffdshow to get the subtitles, but that's an always on/off type workaround.

I really want a UI option to turn it on and off and I think I can program it but I don't know how to get started.
I took a look at the direct show graph using Grapheditplus, I noticed that teletext is implemented off the VBi line from my Hauppauge capture card. I also noticed that there is a kernel tee splitter between the two, which means I could hook up CC to the second split. I did just that using Grapheditplus and sent the output to the video renderer to check the results. It worked.

Now the question is, how can I implement what I did in Grapheditplus inside MP?
As far as I know I need to know the following,
Where in the source code are the graphs managed and controlled? I assume I can follow the same logic as teletext.

Once the functionality is implemented, how do I control it from the UI? Should I modify the My TV plugin, or can I implement another plugin that plugs into My TV?

Lastly now that 0.2.3 is stable I doubt anyone wants me to mess with it to put CC in, should I be setting my sights on 2.0 instead?

I'm a C# programmer but Direct X and TV isn't my specialty, nevertheless I use MP for my HTPC and I would like to add in the support. Any help would be appreciated. Thanks.
