I have just checked out MC 14 on my HTPC.
I have to say that this seems as a very impressing tool, and I seriously evaluated using this instead of Windows 7 Media Center.
This is why I did not do it:
I'm having a Floppy DTV-C card that allows me to view all my cabel channels trought the TV. MC 14 does not support DVB-C, thus making it useless for me.
This is the main reason. I assume that this should be quite easy to solve, but it has to be a majour issue for european users.
In addition:
There seems to be some special demands/issues for the My Movies integration (my movies only shows up named VIDEO_TS). I have 600+ movies, restrukstructuring how they are stored will not be done.
By some odd reason, my stereo sound (using WASAPI) was outputted as multichannel output instead of stereo. I assume this is easy to fix, but due to the previous two issues I did not use any energy on solving this.
