This was NOT a rant. But 95% of all user complaints we get, especially 
those with playback problems, do have issues with MKV files they 
downloaded from the internet, containing Realvideo. Many of them claim 
they are 'advanced users' , so sorry if i questioned your status of 
being an experienced video user beforehand. It seems you know your stuff 
quite well, and also did some searching before turning here.

We have roughly 100,000 downloads / month my friend, and we get less 
than 5 complaints like this in an average. Even if we assume only 1% of 
them find their way to this list, this makes roughly 500 ( a 0.5% ratio 
) users with problems. Just because our filters give problems on your 
machine, you shouldnt judge about the status of our project just based 
on this negative experience of yours. We have MANY happy users, and 
their number is growing every month.

You said earlier that you are having a lot of different DirectShow 
filters installed on your machine, and i am convinced that you are 
facing an incompatibility of one of these filters with ours. It could be 
helpful for us to find out what's causing the problems, and in return we 
could work together to make the movie play on your machine. Of course, 
only if we find the way back to normal communication, and stop the 
insults and prejudices from both sides.

A first step would be to use matroskadiag.exe, as i was telling you 
above on the file. Alternatively, as you are an experienced user, you 
could use Microsoft's DirectShow diagnostic tool, graphedit.exe, and try 
a 'file' 'render media' on your MKV file, and send me a screenshot of 
your playback graph. Please note that Graphedit is a very helpful tool 
for all kinds of playback problems on DirectShow, so as an advanced user 
you should have it anyhow.

Peace :-) ??
