If someone is porting myth to windows they probably want to keep as much as
possibel, like internal audio/video decoders and all that stuff.
Messing with directshow just to make use of a video renderer is probably
overkill since you need a custom filter.
I guess it's probably easier to use directdraw or something directly.

If i remeber correctly, there is a few filters in directshow that can be
used to feed a filter graph or get data from a filter graph.
I think it was well "hidden" somewere in the docs.
I noticed this after i had written a filter for dscaler so it could use
directshow based tv cards.
But those filters is probably to simple to be of any real use.

There is a source filter in dsmyth, it communicates directly with the
backend to get the data.
But, i haven't done any coding on it lately so it's not up to date with svn
and livetv channel changing is very experimental (if things go bad it it
goes realy bad and can't recover).
And there is a few intresting problems with channel changing and dynamic
filter graf rebuilding.
