Would the advantage that the matroska container has in editing make it worth the effort to do the conversion? John

You can do everything with Ogg as you can with Matroska. It's just done differently. If you want to do lossless editing on the frame level, well, you need another codec for that. We're not talking about the ability to edit. We're talking about the container format's ability to store information about how to play content in an "edited way". One could argue that such information belongs in an "effects" codec, rather than in the container itself. -- "The question is no longer between violence and non-violence; It is between non-violence and non-existence." - Martin Luther King, Jr

As Arc says, there's not reason you can't write an editor that works with Ogg natively.> We're not talking about the ability to edit.
