thanks, I was just going to ask you to do the merging.
as for Matroska... it allows several things other video containers cannot do - such as storing sound in .ogg format. it also provides much better compression\quality ratio then most formats (including .wmv and many others).
wheither all this worth making people to install another codec or not is quite a debate over here :\ I hope one day I'll convince our video-ripping guy to betray his "top-tech" .mkv for something more popular. Until then it's .mkv, I guess.
But as for me, I had ffdshow installed anyways long time ago, so I never had any problems with .mkv.
