If you want to burn to a BD-R and play in standalone BD players, download the AVCHD and MKV, and remux as a BDMV folder in tsmuxer, with the AVCHD video (which is BD-compatible) and MKV audio (which is the DTS-HD).
If you just want an MKV file to watch on PC or hardware players, then just download the MKV and boom, you're done.
