Plextor px-504UF will not work with Microstudio or Hoster

[Audio X-Press]

I saw in another thread that by a MTU moderator that said that the only Plextor dive that wouldn't work was the Plextor pxw504. So I am wondering if the Plextor PX-504UF or Plextor PX-504A will work for ripping and burnig CD+G's & MP3+G's.

Also, I noticed that CAVS makes a MP3+G disc that they said can only be played on a CAVS MP3 player. However, that seems to be a little bit of a marketing ploy considereing that the player is $600.00. Does anybody know if the MTU software and supported drives work with MP3+G's?

Replies are greatly appreciated.
