How to Convert M2TS to MKV

As we know, M2TS and MKV are both containers; they have no bearing on the amount of compression used. I believe an M2TS taken from a Blu-ray or AVCHD disk is going to be a bit bigger than an MKV with the same contents, because the M2TS contains extra file structure information that you don't need. Additionally, when repacking an M2TS into an MKV, people usually remove any audio streams they don't want. There's no point in keeping a French dub of an American film if you can't speak French. If you want to use a stand-alone device like a HTPC, Popcorn Hour or a Western Digital player, you'll probably have better compatibility with the MKV container.
