I've understood that RevolverHD can burn AVCHDs onto DVD-R.
But can I burn onto BD-R as well?

I have BD-R drive made by third party.

BD-R burning

Sorry but RevolverHD only supports burning of DVDs containing AVCHD and AVREC file structures (using UDF 2.50).

We don't have any driver support for Blu-ray players.
