Yeah, that's the idea behind taking it down eventually, I don't intend to do MKV for the other two. If someone specifically needs the MKV format, they can always remux the AVCHD's or BD's m2ts file to MKV and otherwise thinking back, it seems to have been pointless to rush out the MKV when the BD will be using the same stream and the AVCHD looks very good (personally, I can't tell the difference between the MKV and AVCHD).

But then we're getting a lesser quality mkv by creating an mkv from the AVCHD unlike this where the mkv is higher quality. Why the hate for mkv? It's the perfect format for viewing on media players. Myself I want to watch this on my HDTV and the mkv can easily play on either my media players or my blu-ray player which supports mkv or even my tv itself which also plays mkv.
