I cant understand why nero doesnt have a plugin for ogg, but anyways..
Im not sure if theres another burning program that works as good as nero does, and has ogg capability, but i doubt it.
There are a few options though.
1. Convert the ogg files to wav before burning. Takes up some hd space though.
2. Convert to mp3 (320kbps to minimise quality loss) then burn. (still takes up hd space, and there may be a tiny loss in quality).
3. Use Soundforge by sonic foundry or another similar program that has a built in burning plugin. Not free though, but its what i use.
