I wish someone would write a mac version of mkv2vob so that I could delete my windows partition. Why oh why can't they port this incredible app

Open with VLC and click file then save as/convert

I tried that but it whenever I tried to convert files that way they wouldn't play on my PS3

There's a GUI for MKVextract (called iMKVextract) here. I've only used it once, quite some time ago, so I can't guarantee anything, but it's worth trying.

Yes. It is good.iSquint and VisualHub are also good.
iSquint and VisualHub, the popular video converter on Mac OS X have now gone open source. They also has got new names, Film Redux (VisualHub) and PunyVid (iSquint). As you may or may not know, the developer, Techspanion has closed shop and after an outcry from fans, it has released the source code. Here is a tutorial on how to build them.
