Yes there is more than one way to go from Vorbis to NetMD.
The program is called M3U2SB, and can be found
HERE.This program takes mp3 and vorbis files, decodes them into wavs, and then feeds them to SimpleBurner as a virtual CD image, either using Nero or Daemon Tools. (The latter is freeware, but both work just as well.) SimpleBurner then encodes and records the tracks onto your MD, complete with titles based on the original mp3 and vorbis tags.
You must have a working copy of Sony's SimpleBurner for this to work, which you will either have received with your NetMD unit, or you can download it from various places on the web.
It certainly works quite well, as a one program solution.
Or, you can use foobar to take all of your tunes in any format, and get it to write them as replaygained wavs, with the track titles as file names. Then import these wavs onto your NetMD player via either Sonicstage or OpenMG jukebox. If you maintain your replaygain info, etc, you end up with a nice disc with all the tracks of consistent volume, and titles.
I personally use the second approach, recording mixtures of Wavpack, mp3, mpc and vorbis files onto MD. B)
If you need more detailed instructions, I can probably post something in more detail.
Hope this helps
