[MPlayer-users] realaudio index

[Raphael Clifford]

Is there any way to skip/seek in a readaudio file.  When I attempt to I get
"Cannot seek in this file."

mplayer -idx doesn't make any difference to this. I tried mplayer 
-forceidx but unfortunately that segfaulted. I will provide a backtrace 
if it turns out I didn't make a stupid mistake.

MPlayer dev-CVS-030729-11:38-3.1.  redhat 7.3 with gcc 3.1 installed and 
mplayer compiled from daily CVS snapshot with live enabled.

Here is the output of mplayer -v
