I am the originator of this bug report. You can go ahead and close it down, mplayer recently took its turn at disliking .rmvb videos, and when I tried xine, it worked!
.rmvb's now play just fine in xine (though god-awfully slow in gxine, for whatever reason). Thanks, Clayton -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
