Well, anyone who has poked the dshow framework would have noticed the large number of filters that seem to accumulate (http://www.cccp-project.net/smf/index.php?topic=1760.msg11464#msg11464) over (http://www.cccp-project.net/smf/index.php?topic=1751.0) time (http://www.cccp-project.net/smf/index.php?topic=1406.msg8593#msg8593). Even with the default windows install you start out with 110 filters or so. Anyway, this is never really a problem as unused filters just sit there benignly -- which is why you should never try the following :p.
I wanted to see how many filters you could cut out of the directshow list and still play stuff, everything listed here (http://www.cccp-project.net/wiki/index.php?title=FAQ#Supported_Formats) to be precise.
To cut a long story short, here's what I ended up with:
[DirectShow Filters]
[3 detected]
1> ffdshow Audio Decoder
Filename: C:\Program Files\Combined Community Codec Pack\Filters\FFDShow\ffdshow.ax
CLSID: {0F40E1E5-4F79-4988-B1A9-CC98794E6B55}

2> ffdshow Video Decoder
Filename: C:\Program Files\Combined Community Codec Pack\Filters\FFDShow\ffdshow.ax
CLSID: {04FE9017-F873-410E-871E-AB91661A4EF7}

3> Video Renderer

CLSID: {6BC1CFFA-8FC1-4261-AC22-CFB4CC38DB50}

These three play everything listed above, bar WavPack and .flv (which requires their own filters). There are a few interesting tidbits here:
o You don't need a source filter as long as you register haali's splitter as the default handler for avi/mkv/ogm/mp4/ts
o you don't need a renderer, haali's splitter can connect to his renderer without a directshow entry. In theory VMR7/9 would work too, but... ewwww
o you don't need vsfilter registered, haali's splitter can be set to force load it whenever subtitles are detected.
The one thing I can't work out is why the Video Renderer is required, but that's a mystery for another day ;)
