AudioDVD to a format for blue ray?

[alc112]

Hi!
I'm sorry for the confusing title.

This is the thing:
I found out that bluray players do not play Audio DVDs.
And my question is what can i do with a custom audio dvd i downloaded to be played in my blue ray player Sony BDP-S360

I read somewhere that I should convert it to something like truedts (i don't remember)

So i guess I should fisrt extract the audio tracks and make the equivalent DVD audio for bluerays. (i want to keep the 5.1 audio)

but I don't have blue ray burner. I have to use dvd discs instead.
Can you enlighten me?

Might be worth trying multiAVCHD.The author has included audio disc support for playback on BD players.
