UPDATES:

I'm preparing the final video right now, using a bitrate of 20,000kbps (that should be more than enough to preserve the quality of the original HD-DVD); I prepared the subtitles: full and SDH for english, and full plus forced for italian, french, german and spanish.

Do you still want the DTS-HD MA audio?

At the end, I've left enought space (I think) to discard the DTS I've made from the HD-DVD DD+ and replace it with the DTS-HD MA... but it must be around 3.5GB... if so, please send me a P.M. with the uploading link - THANKS in advance!
