When will be an update to Twonky 5

I just bought a 4Tb unit and i find i can´t use the twonky because my ps3 doesn´t recognize the format and this old version can´t transcode the file.

Must i return the wd because they are not going to give us an update?

Where must i ask?

Thank you.

There is a firmware update coming, and it will probably include a Twonky update as well.  However, it will probably be the same update as was released in the My Book World just recently.  I think it was version 5.1.4-1.
