["Valerio Pachera" <sirio81@xxxxxxxxx>]

Hi all, this is my first message in this mailing list :)
I'm using dvd::rip 0.52.5 on kubuntu linux 6.06.
I've got a movie (an anime) that contain 2 audio tracks.
I want keep both in my ogm.

I readed the guide
http://www.exit1.org/dvdrip/doc/gui-gui_transcode.cipp#gui_tc_aud_targtrack
that report

"If you want to select a different DVD audio track for transcoding or
even multiple audio tracks, hit on the Multi... button."

I can't see this button anywhere!!!
Can you help me? Maybe send a screenshot of that button?

Thanks!
